Internet-Draft Mesh Protocol Reference October 2024
1. Introduction
This document describes the Mesh Service protocol supported by Mesh
Services, an account-based protocol that facilitates exchange of data
between devices connected to a Mesh profile and between Mesh
accounts.
Mesh Service Accounts support the following services:
* Provides the master persistence store for the Catalogs and Spools
associated with the account.
* Enables synchronization of Catalogs and Spools with connected
devices.
* Enforces access control on inbound Mesh Messages from other users
and other Mesh Services.
* Authenticates outbound Mesh Messages, certifying that they comply
with abuse mitigation policies.
A Mesh Profile MAY be bound to multiple Mesh Service Accounts at the
same time but only one Mesh Service Account is considered to be
authoritative at a time. Users may add or remove Mesh Service
Accounts and change the account designated as authoritative at any
time.
The Mesh Services are build from a very small set of primitives which
provide a surprisingly extensive set of capabilities. These
primitives are:
Hello Describes the features and options provided by the service and
provides a 'null' transaction which MAY be used to establish an
authentication ticket without performing any action,
CreateAccount, DeleteAccount Manage the creation and deletion of
accounts at the service.
Status, Download, Upload Support synchronization of Mesh containers
between the service (Master) and the connected devices (Replicas).
Connect Initiate the process of connecting a device to a Mesh
profile from the device itself.
Post Request that a Mesh Message be transferred to one or more Mesh
Accounts.

Internet-Draft Mesh Protocol Reference October 2024
Although these functions could in principle be used to replace many
if not most existing Internet application protocols, the principal
value of any communication protocol lies in the size of the audience
it allows them to communicate with. Thus, while the Mesh Messaging
service is designed to support efficient and reliable transfer of
messages ranging in size from a few bytes to multiple terabytes, the
near-term applications of these services will be to applications that
are not adequately supported by existing protocols if at all.
2. Definitions
This section presents the related specifications and standard, the
terms that are used as terms of art within the documents and the
terms used as requirements language.
2.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
2.2. Defined Terms
The terms of art used in this document are described in the _Mesh
Architecture Guide_ [draft-hallambaker-mesh-architecture].
2.3. Related Specifications
The architecture of the Mathematical Mesh is described in the _Mesh
Architecture Guide_ [draft-hallambaker-mesh-architecture]. The Mesh
documentation set and related specifications are described in this
document.
2.4. Implementation Status
The implementation status of the reference code base is described in
the companion document [draft-hallambaker-mesh-developer].
3. Mesh Protocols
The Mesh specifies two separate types of protocol interactions:
Mesh Service Protocol A synchronous protocol supporting interactions
between devices and a Mesh Service Host and between Mesh Service
hosts.
Mesh Messaging Protocol An asynchronous protocol that supports
Hallam-Baker Expires 17 April 2025 [Page 6]
Internet-Draft Mesh Protocol Reference October 2024
interactions between devices connected to the same account and
between accounts.
The Mesh Messaging Protocol uses the Mesh Service Protocol as
transport. The Mesh Service Protocol in turn makes use of Reliable
UDP Datagram (RUD) [draft-hallambaker-mesh-rud] for framing and
authentication of individual requests and responses. These RUS
packets are in turn exchanged over either HTTPS (i.e. a Web Service)
or directly over UDP.
(Artwork only available as svg: see https://www.ietf.org/archive/id/
draft-hallambaker-mesh-protocol-16.html)
Figure 1: Protocol Layering
Mesh Services MUST support the HTTPS binding and MAY support the UDP
binding.
4. Mesh Service
A Mesh Service is a minimally trusted service. In particular a user
does not need to trust a Mesh service to protect the confidentiality
or integrity of most data stored in the account catalogs and spools.
Unless the use of the Mesh Service is highly restricted, a user does
need to trust the Mesh Service in certain respects:
Data Loss A service could refuse to respond to requests to download
data.
Integrity (Stale Data) The use of Merkle Trees limits but does not
eliminate the ability of a Mesh Service to respond to requests
with stale data.
Messaging A service could reject requests to post messages to or
accept messages from other mesh users.
This risk is a necessary consequence of the fact that the Mesh
Service Provider is accountable to other Mesh Service Providers
for abuse originating from their service.
Traffic analysis A Mesh Service has knowledge of the number of Mesh
Messages being sent and received by its users and the addresses to
which they are being sent to or received from.
The need to trust the Mesh Service in these respects is mitigated by
accountability and the user's ability to change Mesh Service
providers at any time they choose with minimal inconvenience.
Hallam-Baker Expires 17 April 2025 [Page 7]
Internet-Draft Mesh Protocol Reference October 2024
It is possible that some of these risks will be reduced in future
versions of the Mesh Service Protocol but it is highly unlikely that
these can be eliminated entirely without compromising practicality or
efficiency.
4.1. Data Model
The design of the Mesh Service model followed a quasi-formal approach
in which the system was reduced to schemas which could in principle
be rendered in a formal development method but without construction
of proofs.
Like the contents of Mesh Accounts, a Mesh Service may be represented
by a collection of catalogs and spools, for example:
Account Catalog Contains the account entries.
Incident Spool Reports of potential abuse
Backup of the service MAY be implemented using the same container
synchronization mechanism used to synchronize account catalogs and
spools.
4.2. Partitioning
Mesh Services supporting a large number of accounts or large activity
volume MAY partition the account catalog between one or more hosts
using the usual tiered service model in which a front-end server
receives traffic for any account hosted at the server and routes the
request to the back-end service that provides the persistence store
for that account.
In addition, the Mesh Service Protocol supports a 'direct connection'
partitioning model in which devices are given a DNS name which MAY
allow for direct connection to the persistence host or to a front-end
service offering service that is in some way specific to that
account.
5. Protocol Bindings
The protocol binding maps the abstract protocol definition specified
in this document to the network protocol format.
* Discovery of network services.
* Construction of the payload data by serializing request and
response messages.
Hallam-Baker Expires 17 April 2025 [Page 8]
Internet-Draft Mesh Protocol Reference October 2024
* Authentication of the payload data.
* Confidentiality controls to protect against traffic analysis
Currently only one protocol binding is specified: JSON-BCD
Application Binding [draft-hallambaker-jsonbcd] over Reliable User
Datagram (RUD) [draft-hallambaker-mesh-rud].
*JSON-BCD Application Binding* specifies the means by which data
types such as 'integer' and 'datetime' etc. given in this document
are serialized using JSON/JSON-B encoding.
*Reliable User Datagram* offers a presentation layer over a choice of
HTTP or UDP transport.
6. Mesh Service Operations
The Mesh Service operations are divided into the following functional
groups:
Service Description Describes the service.
Account Management Operations used to create, reclaim, and delete
accounts.
Persistence Store Management Operations used to synchronize
persistence store data across connected devices. [May be replaced
in a future revision]
Device Connection Operations used by devices requesting connection
to the account.
Publication Operations allowing a watched document to be posted to
the service and claims made on the document returned to a device.
Cryptographic Cryptographic operations, including threshold
operations performed by the service.
Messaging Exchange of messages between Mesh Services.
6.1. Service Description
The Hello transaction is used to determine the features supported by
the service and obtain the service profile.
The request payload only specifies that is is a request for the
service description:
Hallam-Baker Expires 17 April 2025 [Page 9]
Internet-Draft Mesh Protocol Reference October 2024
{
"HelloRequest":{}}
The response payload describes the service and the host providing
that service:

The current revision of the specification is designed for small scale
deployments in which the service is provided by a single host. The
approach will require revision in future versions to fully support a
service being provided by multiple hosts with accounts being
transferred between the hosts to allow balancing of load.
6.2. Account Management
There are three account management operations:
BindAccount Create an account bound to a service address.
UnbindAccount Delete an account bound to a service address
RecoverAccount [TBS] Reclaim an account using a recovered primary
secret.
The BindAccount operation is used to create User and Group accounts.
Currently, these account types are distinct. This may change in
future releases.
6.2.1. Bind Account
A User Account is bound to a Mesh Service by completing a BindAccount
operation with the service.
The BindAccount transaction is unique in that it can fail to complete
for reasons that are outside the scope of the Mesh specifications.
Creation of an account might require payment to be made or
authentication of the user's credentials. It is thus quite normal
for the result of a CreateRequest to be the account being created in
an 'on hold' state which can only be changed out of band.

If the request is at least partially successful, a BindResponse
message is returned. In the case of partial success, a description
of the request status and link to a Web page providing further
details MAY be returned.
The request payload contains all the information needed to create the
account:
* The account address
* The account profile
Since there is no Access Catalog until the account is created, the
Bind Account request and subsequent requests used to initialize the
access catalog for the account MUST be authenticated by the Account
Authentication key.
Alice requests creation of the account alice@example.com. The
request payload is:

It is likely that a future revisions of the specification will
specify the host(s) to which future account service operations are to
be directed. This would allow the account management operations to
be separated from the account maintenance operations without
requiring the traditional tiered architecture in which every
interaction with a service is first routed to a host that cannot
perform the required action so that it can be directed to the host
that can.
6.2.1.1. Bind Group Account
Mesh Group Accounts are created in the same manner as user accounts
except that the ProfileGroup is specified.
6.2.1.2. Account Recovery
Should all the administration devices be lost, an account MAY be
recovered by the process of recovering the profile master secret and
using it to access the account through the account authentication
key.

6.2.2. Unbind Account
An account registration is deleted using the UnbindAccount
transaction.

"UnbindResponse":{

6.2.2.1. Account Transfer
Should a user wish to transfer their account to a new service
provider, they first use the Bind Account operation to bind the
account to the new service provider, then populate the account entry
at the new account using the account authentication key.
Only after the new account binding has been completed and is ready
for use, is the unbind operation used to delete the account entry at
the old service provider.
Future versions of the protocol will elaborate on this mechanism so
that the change of address can be signaled to connected devices and
parties sending messages to the account.
6.2.3. Account Recovery and Transfer.
Account recovery is necessary in the case that user has lost control
of every administration device connected to the account and must re-
create the account profile and bind a new set of administrative
devices. Account transfer is the process of unbinding an account
from one service and rebinding it to a new one.
These capabilities are both critical to the long term success of the
Mesh but have been deleted from the current revision of the
specification as their implementation is interdependent on the
architecture of the callsign registry.

6.3. Persistence Store Management
All the state associated with a Mesh profile is stored as a sequence
of DARE Messages in a Dare Container. The Mesh Service holding the
master copy of the persistence stores and the devices connected to
the profile containing complete copies (replicas) or partial copies
(redactions).
Thus, the only primitive needed to achieve synchronization of the
profile state are those required for synchronization of a DARE
Container. These steps are:
* Obtain the status of the catalogs and spools associated with the
account.
* Download catalog and spool updates
* Upload catalog updates.
To ensure a satisfactory user experience, Mesh Messages are
intentionally limited in size to 32 KB or less, thus ensuring that an
application can retrieve the most recent 100 messages almost
instantaneously on a high bandwidth connection and without undue
delay on a slower one.
6.3.1. Status
The status transaction returns the status of the containers the
device is authorized to access for the specified account together
with the updated Device Connection Entry if this has been modified
since the entry presented to authenticate the request was issued.
Alice adds an entry to her bookmark catalog. Before the bookmark can
be added, the device synchronizes to the service. The
synchronization process begins with a request for the status of all
the stores associated with the account that it has access rights for:

Bug: The current version of the reference code is only returning the
digest values for the outbound store.
6.3.2. Download
The download transaction returns a collection of entries from one or
more containers associated with the profile.

Internet-Draft Mesh Protocol Reference October 2024
The service MAY limit the number of entries returned in an individual
response for performance reasons.
The previous status operation has reported that a new envelope has
been added to the credential store. The device requests this data
from the service:
The response contains the requested envelope:
Future: The current implementation of the download operation is
limited by the capabilities of the HTTP binding of the RUD transport.
A future binding allowing operations that consist of a single request
followed by a sequence of responses will allow much greater
flexibility.
Future versions of the protocol may support optional filtering
criteria so that the service only returns objects matching specific
criteria and/or only return certain parts of the selected messages.
6.3.3. Transact
The transact transaction appends envelopes to one or more stores.
The operation is atomic, that is either all the changes specified
will be made to the stores or none will. This ensures that
simultaneous attempts to update a store do not result in race
conditions allows Mesh stores to provide ACID (Atomicity,
Consistency, Isolation, Durability) properties to the applications
they serve.
Clients SHOULD check to determine if updates to a container conflict
with pending updates on the device waiting to be uploaded. For
example, if a contact that the user modified on the device attempting
to synchronize was subsequently deleted. The means of resolving such
conflicts is not in the scope of this specification.
Each update to a catalog or container specifies the expected
container index and apex digest. This provides a strong guarantee of
consistency. The service MUST verify each update to check that the
Merkle Tree values specified are consistent with the store entries
and that the signature on the apex value (if specified) is valid and
correct.
Services MAY impose limits on the size and number of additions
performed in response to a TransactRequest message to ensure that
processing time does not degrade performance for other users.
The request payload specifies the data to be appended to the stores.

6.4. Device Connection
In order to support the wide range of affordances supported by
devices, four device connection interactions are currently specified.
The use of these mechanisms is described in
[draft-hallambaker-mesh-architecture] and the interactions themselves
are described in section ??? following.
Device connection operations are always issued by a device requesting
connection to a Mesh account and must therefore be authenticated
under the device profile rather than the account profile. Two device
connection operations are currently defined:
Connect Requests connection to the account.
Complete Polls for completion of a connection request.
Since the second operation is merely polling for completion of the
transaction requested by the first, it is likely that these will be
combined in a future revision of the specification.
6.4.1. Connect
If the connection request is initiated by the device being connected,
the device constructs a RequestConnection message which is posted to
the Mesh Service using the Connect operation.
If the Connect operation is accepted (i.e. the service determines it
is not abuse), the service constructs an AcknowledgeConnection
message which is forwarded to the inbound spool of the account to
which connection is requested. The requesting device receives a copy
of the AcknowledgeConnection message and the profile of the account
it is requesting connection to.
As described in the following section, the AcknowledgeConnection
message contains the request details presented by the device and a
nonce value generated by the service. This nonce value is used to
compute the witness value that will be used for mutual authentication
of the device and account.
The connect request is made to the service, not the account. The
payload contains the enveloped connection request:

6.5. Publication
[Future: Consider eliminating this mechanism entirely and instead
using messaging flows. The means of achieving this should become
better apparent when the problem of publishing large messages via a
pull mechanism is considered.]
The Publication mechanism allows content to be published through a
Mesh Account and retrieved by means of the EARL mechanism described
in Uniform Data Fingerprint [draft-hallambaker-mesh-udf]. This
mechanism is used in certain flows supported by the Mesh Device
Connection and Contact Exchange functions. There are two operations:
Claim Post a claim to a published document
PollClaim Check to see if a claim has been posted.
Content is published by appending an entry to an account's
Publication catalog by means of a Transact operation. The content
may then be retrieved by issuing a claim to the account specifying
the publication identifier that is authenticated under the value
specified in the EARL.
Use of the Publication catalog to post content necessarily requires
that the content be smaller than the maximum message size imposed by
the Mesh Service so that it can be uploaded to the service by means
of a Transact transaction.
Publication of large data items will require modification of the
protocol to support use of a detached message body. Transfer of a
detached message body is outside the scope of this document.
6.5.1. Claim Transaction
The claim transaction is used to post a claim to a document published
by means of an EARL. The claim interaction is used in the Static QR
Code connection interaction but MAY be used for other purposes as
required by Mesh applications.
Hallam-Baker Expires 17 April 2025 [Page 40]
Internet-Draft Mesh Protocol Reference October 2024
A claim is made by sending a ClaimRequest message to the service to
which the publication is posted. The service responds with a
ClaimRespose message specifying the success or failure of the claim.
A device is preconfigured during manufacture and a Device Description
published to the EARL:
The client claiming the publication creates a claim message
specifying the resource being claimed and the address of the Mesh
account making the claim.

The device waiting to be connected uses the PollClaim transaction to
receive notification of a claim having been posted.
6.5.2. PollClaim Transaction
The PollClaim transaction is used to discover if a claim has been
posted to a published document.
When an authenticated, authorized request is made, the service
responds with the latest claim posted to the publication.
The device in the example above periodically polls the service to
which the device description is published to find if a claim has been
registered.
The PollClaimRequest contains the account to which the document is
published and the publication ID:

6.6. Cryptographic
The Operate transaction is used to perform one or more cryptographic
operations using private key material recorded in the Threshold
Catalog. Such operations typically represent one part of a threshold
key operation divided between the service and a device connected to
an account.
As with all operations involving the Access catalog, the request MUST
meet the authentication criteria specified by the catalog entry.
These typically include the request being authenticated by a specific
key.Key Agreement

To make use of the access entry, a request is made that specifies the
key share to be operated on and the public key parameters to perform
the agreement with.
The request payload:
{
"OperateRequest":{
"AccountAddress":"groupw@example.com",
"Operations":[{

*Future*: Currently, the access catalog is encrypted under the
service encryption key. It would be better to encrypt the catalog
under an encryption key specified by the service during the process
of account binding. This would allow a service to assign a unique
encryption key to each account and limit access to that key to the
hosts servicing that specific account.
6.6.1. Generate Key Shares
Generation of threshold key shares is planned but not currently
supported.
Hallam-Baker Expires 17 April 2025 [Page 47]
Internet-Draft Mesh Protocol Reference October 2024
6.6.2. Threshold Sign
Threshold signature is planned but not currently supported.
6.7. Messaging
Mesh Messaging is an asynchronous messaging service that allows
exchange of information between devices connected to a Mesh account
and between Mesh users.
To enable effective abuse mitigation, Mesh Messaging enforces a four-
corner communication model in which all outbound and inbound messages
pass through a Mesh Service which accredits and authorizes the
messages on the user's behalf.
(Artwork only available as svg: see https://www.ietf.org/archive/id/
draft-hallambaker-mesh-protocol-16.html)
Figure 2: The Mesh Four Corner Messaging Model
The Post transaction is only used to exchange messages between
services. The client sends and receives messages through
interactions with the outbound and inbound spools of the account.
6.7.1. Sender.
To send a message, the client creates the Mesh Message structure,
encapsulates it in a DARE Message and appends the message to the
Outbound spool of the account using the Transact operation..
The DARE Message MUST be signed under the account signature key.
The Mesh Service receiving the message from the user's device MAY
attempt immediate retransmission or queue it to be sent at a future
time. Mesh Services SHOULD forward messages without undue delay.
6.7.2. Outbound Service
The Post transaction forwarding the message to the destination
service carries the same payload as the original request but is
authenticated by the service forwarding it. This authentication MAY
be my means of either profile or ticket authentication.
>>>> Unfinished ProtocolPostServiceService
[Not Yet Implemented]
Hallam-Baker Expires 17 April 2025 [Page 48]
Internet-Draft Mesh Protocol Reference October 2024
After the message has been sent, the service updates the message
status on the outbound spool.
Services SHOULD implement Denial of Service mitigation strategies
including limiting the maximum time taken to complete a transaction
and refusing connections from clients that engage in patterns of
behavior consistent with abuse.
The limitation in message size allows Mesh Services to aggressively
time out connections that take too long to complete a transaction. A
Mesh Service that hosted on a 10Mb/s link should be able to transfer
20 messages a second. If the service is taking more than 5 seconds
to complete a transaction, either the source or the destination
service is overloaded or the message itself is an attack.
Imposing hard constraints on Mesh Service performance requires
deployments to scale and apply resources appropriately. If a service
is attempting to transfer 100 messages simultaneously and 40% are
taking 4 seconds or more, this indicates that the number of
simultaneous transfers being attempted should be reduced.
Contrawise, if 90% are completed in less than a second, the number of
threads allocated to sending outbound messages might be increased.
6.7.3. Inbound Service
The inbound service MUST subject inbound messages to Access Control
according to the credentials presented in the DARE Message payload.
After verifying the signature and checking that the key is properly
accredited in accordance with site policy, the service applies
authorization controls taking account of:
* The accreditation of the sender
* The accreditation of the transmitting Service
* The type of Mesh Message being sent
* User policy as specified in their Contact Catalog
* Site policy.
6.7.4. Recipient
Messages are received by synchronizing the outbound spool.
Hallam-Baker Expires 17 April 2025 [Page 49]
Internet-Draft Mesh Protocol Reference October 2024
7. Access Control
[This section to be expanded in future drafts]
Access control is effected through the usual division of
authentication and authorization.
Authentication of operation requests is performed by the RUD layer
[draft-hallambaker-mesh-rud] .
7.1. Direct authorization
Any request authenticated under the profile authentication key is
authorized to perform any account operation without restriction.
7.2. Access Catalog authentication
If the authentication key presented has a matching Access Catalog
entry, the device is authorized to perform operations as specified in
that entry.
8. Message Interactions
Message interactions are asynchronous interactions that occur between
devices connected to the same account or between accounts.
All messages are signed by the sender and encrypted under the
encryption key of the recipient if this is known to the sender.
8.1. Message PIN Interaction
The Message PIN Interaction is used to register and validate PIN
codes used to authenticate certain transactions. This interaction
allows a PIN code issued by one device to be consumed by another
allowing for greater convenience in managing devices or contact
exchange.
For example, Alice might delegate the PIN code issue privilege to her
mobile device without delegating the administration privilege to that
device. This would allow Alice to use her mobile device to initiate
the connection of a large number of devices to her Mesh as her house
is being built and approve them later using her administrative
device.
Use of the Message PIN interaction is optional. An application that
issues a PIN code to authenticate a message MAY store the PIN value
within the application without persisting it to external storage.
Hallam-Baker Expires 17 April 2025 [Page 50]
Internet-Draft Mesh Protocol Reference October 2024
Derivation of the SaltedPin, MessageId and Witness values from their
respective inputs is described in the Schema Reference
[draft-hallambaker-mesh-schema].
8.1.1. Registration
To register a PIN code to an Account, a device:
* Generates the PIN code value
* Calculates the SaltedPin value for the specified Action
* Calculates the PinId binding the specified SaltedPinto the
Account.
* Creates and signs MessagePin containing the SaltedPin, Action and
Account values with the MessageId value PinId.
* Appends the MessagePinvalue to the Administration Spool of the
Account.
Note that this construction provides limited protection against
forgery attacks by a party with access to the MessagePin. A party
with such access can use it to construct the witness value required
to authenticate a request.
PIN Code values consist of an opaque sequence of octets represented
as a UDF nonce value. Codes are presented in canonical UDF form,
i.e. Base32 encoding separated into groups of 4 characters. The PIN
value is converted to binary form for calculation of the SaltedPin,
thus ensuring that the canonical form of the PIN value is used.
8.1.2. Authentication
The PIN Code value is passed out of band to a user who will enter it
into a device to authenticate a request made to the issuer.
A request that MAY be validated by means of a PIN is a subclass of
MessagePinValidated and contains the following fields:
AuthenticatedData A DARE Envelope containing the data that is
authenticated.
ClientNonce A nonce value used to prevent certain replay attacks.
PinId Digest value binding the SaltedPinto the Account.
PinWitness Witness value calculated as KDF (Device.UDF +
Hallam-Baker Expires 17 April 2025 [Page 51]
Internet-Draft Mesh Protocol Reference October 2024
AccountAddress, ClientNonce)
The device uses the PIN code and Action identifier corresponding to
the desired request to calculate the SaltedPin value in the same
manner as during registration. This value is then used to calculate
the PinId and PinWitness values.
8.1.3. Validation
The PIN code is validated by performing the steps of:
* Calculating the SaltedPin value from the PIN code and Action
* Calculating PinId from SaltedPin and Account
* Retrieving a MessagePin from the Administration spool with the
MessageId PinId.
* Calculating the PinWitness value from SaltedPin, ClientNonce and
AuthenticatedData and checking this matches the value specified in
the message.
* Performing the requested action.
* Posting a Complete message to the Administration Spool of the
Account marking the PIN code as used.
This process can fail at multiple points resulting in different error
results:
PinInvalid No PIN code is specified, the Pin code indicates an
unsupported algorithm or the calculated PinWitness does not match
the one specified by the request.
PinUsed The PIN code has been used previously.
PinExpired The PIN code is no longer valid.
Note that in the case that an attempt is made to reuse a PIN, it is
not automatically the case that the first use of the PIN was the one
that was valid and only the second attempt was invalid.
Implementations SHOULD alert the user to the attempted re-use so that
this possibility can be considered and appropriate action taken.
8.1.4. Example
Alice connects a device using a QR code presented by her
administrative device.
Hallam-Baker Expires 17 April 2025 [Page 52]
Internet-Draft Mesh Protocol Reference October 2024
The administration device creates a PIN code and records it to the
Local spool. The message specifies the salted pin value used to
verify attempts to use the PIN, the action for which it is
authorized. Since this PIN has been issued to authorize a device
connection, the roles for which the device are authorized as well.
This allows the connection request to be accepted without asking for
further input from the user.

"Action":"Device",
"Roles":["threshold"
],
"MessageId":"AAKU-MJKW-GRDS-S3ZI-DONH-D6US-4REW"}}
8.2. Completion Interaction
Completion messages are dummy messages that are added to a Mesh Spool
to mark a change the status of messages previously posted. Any
message that is in the inbound spool and has not been erased or
redacted MAY be marked as read, unread or deleted. Any message in
the outbound spool MAY be marked as sent, received or deleted.
Services MAY erase or redact messages in accordance with local site
policy. Since messages are not removed from the spool on being
marked deleted, they may be undeleted by marking them as read or
unread. Marking a message deleted MAY make it more likely that the
message will be removed if the sequence is subsequently purged.
After using the PIN code to authenticate connection of a device in
the previous example, the corresponding MessagePin is marked as
having been used by appending a completion message to the Local
spool.
{
"MessageComplete":{
"References":[{
"MessageId":"AAKU-MJKW-GRDS-S3ZI-DONH-D6US-4REW",
"ResponseId":"MDDD-KNM4-KUZH-QVC4-KWLI-5NBW-T54I",
"Relationship":"Closed"}
],
"MessageId":"NARB-QXHR-HQFR-PCAS-D3L6-YGJX-LXCL"}}
Hallam-Baker Expires 17 April 2025 [Page 53]
Internet-Draft Mesh Protocol Reference October 2024
The completion message is added to the spool in the same upload
transaction that adds the device to the device catalog. This ensures
that both operations occur or neither occurs.
8.3. Contact Exchange Interaction
The contact exchange interaction is used to support unilateral or
mutual exchange of contact information. Contact exchange has three
functions in the Mesh:
* To exchange public key information to allow encryption of messages
sent to and verification of signatures on messages sent from the
contact subject.
* To exchange contact information allowing use of other
communication protocols (e.g. telephone, SMS, xmpp, SMTP, OpenPGP,
S/MIME, etc).
* To request that the recipient grant privileges to accept certain
types of messages from the contact subject.
Registration of the subject's contact information in a registry
service eliminates the need for the first of these functions but not
the other two. To prevent abuse, every Mesh Message is subject to
access control and a Mesh service will only accept a message from a
sender if there is an entry in the Threshold Catalog of the account
that expressly permits delivery of messages of the specified type
that are authenticated by an authorized signature key.
The communication of unsolicited information afforded by the contact
exchange interaction is deliberately limited so that a majority of
users can accept contact exchange requests without prior
authorization. It is however likely that some users will receive a
considerable volume of requests forcing them to require contact
requests be authorized through some form of third party
accreditation.
8.3.1. Remote
The Remote Contact Exchange transaction consists of a sequence of
MessageContact messages sent from the initiator to the responder,
responder to the initiator, etc. While there is in principle no
limit on the number of messages exchanged, most exchanges will be
completed in three exchanges or less:
Initiator to Responder Contains Initiator contact data without
authentication context from the exchange.
Hallam-Baker Expires 17 April 2025 [Page 54]
Internet-Draft Mesh Protocol Reference October 2024
Responder to Initiator (optional) Contains Responder contact data
authenticated under a PIN challenge presented in the previous
message.
Initiator to Responder (optional) Contains Initiator contact data
authenticated under a PIN challenge presented in the previous
message.
Each message provides the recipient with additional information which
MAY motivate the recipient to provide additional contact information
to the sender.

The Mesh Contact Exchange transaction does not provide for validation
of the contact information beyond the binding to the Mesh Account
Address used to perform the exchange.
8.3.2. PIN
Contact exchange requests MAY be authenticated by a PIN code.
Initial contact exchange requests SHOULD include a PIN code value
that can be used to authenticate a response (if given). PIN codes
MAY also be exchanged out of band.
A MessageContact authenticated by means of a PIN code is
authenticated as described in the PIN Interaction section above.
8.3.3. EARL
A MessageContact message MAY be published as an EARL. This allows
contact data to be presented to the recipient on a printed document
such as a business card in machine readable format such as a QR code.
8.4. Group Invitation
The GroupInvitation interaction is used to invite a recipient to join
a Mesh Group. The interaction is essentially a form of contact
exchange except that a sender SHOULD NOT send group invitations
unless there is an existing relationship. Thus the 'first trust'
issues intrinsic to the contact exchange interaction do not apply.
The message specifies the group name and the contact entry for the
group. The contact entry includes the CapabilityDecryptServiced used
to decrypt messages sent to the group when combined with information
provided by the threshold service for the group.
Receipt of a GroupInvitation message does not require a response.

8.5. Confirmation Interaction
The confirmation interaction consists of a RequestConfirmation
message from the initiator followed by a ResponseConfirmation from
the responder.
The RequestConfirmation message specifies the action that is
requested.
The ResponseConfirmation message contains the enveloped
RequestConfirmation message signed by the initiator and the
disposition of the responder, Accept = true if the request is
accepted and Accept = false otherwise.
The service sends out the following request:
{
"RequestConfirmation":{
"Text":"start",
"MessageId":"NAZG-5KBV-D32X-O24L-XTYS-26GV-FC6Z",
"Sender":"console@example.com",
"Recipient":"alice@example.com"}}
Alice accepts the request and returns the following response:

9. Device Connection Interactions
Connection of a device to a Mesh Account combines synchronous and
asynchronous elements and therefore uses a combination of Mesh
Service Protocol and Mesh Messaging interactions.
Four connection interactions are currently defined support connection
of devices with different affordances:
Witness Authenticated For connecting devices that provide data entry
Hallam-Baker Expires 17 April 2025 [Page 59]
Internet-Draft Mesh Protocol Reference October 2024
and display affordances and are connected to a network. The
account the device is to be connected to is entered into the
device which displays a witness code. This code is then compared
with a code displayed on the administration device to authenticate
the request, after which both devices can complete the
interaction.
PIN Authenticated A variation of the Witness Authenticated
interaction in which the connection process is initiated by
creating a PIN value which is communicated to the device by some
out of band means and used to authenticate the connection request.
Dynamic QR Code (PIN) Authenticated For connecting devices that
provide a camera affordance. The user sets the administration
device into 'add device' mode, causing a QR code to be displayed.
The QR code is scanned by the device being connected after which
both devices can complete the interaction. Implementation of this
mechanism is identical to the PIN authenticated scheme except that
the PIN code is presented to the connecting device by means of a
QR code.
Preconfigured (Static QR Code Authenticated) For connecting devices
that have been preconfigured with a device profile identified by
means of a QR Code containing an EARL. The QR code is scanned by
the administration device after which both devices can complete
the interaction.
Each of these interactions provide strong mutual authentication with
minimal user effort.
The witness authenticated connection interaction is intended for use
in cases in which the device is already connected to a network. The
QR code interactions are intended to provide support for acquisition
of networking capabilities as part of the connection process. These
functions are not currently specified. The Static QR Code
Authenticated interaction is intended to support Internet of Things
(IoT) devices which provide minimal interaction affordances.
In each case, the objectives of the device connection interaction are
the same:
* Mutually authenticate the onboarding device and the Mesh such that
the connection interaction only completes if both sides acquire
the authentic profile of the other.
Hallam-Baker Expires 17 April 2025 [Page 60]
Internet-Draft Mesh Protocol Reference October 2024
* To provision the onboarding device with the Mesh ProfileAccount,
and an ActivationDevice and ConnectionDevice record allowing the
device to interact as a member of the Mesh with the set of rights
specified by the user.
* To create a CataloguedDevice record and append it to the Device
catalog of the account to allow the device to be managed within
that account.
* (optional) to acquire networking capabilities to allow the above
to be completed.
The connection of the device to the Mesh Account is achieved through
the creation of the ActivationDevice, ConnectionDevice and
CataloguedDevice records described in
[draft-hallambaker-mesh-schema]. These are created by the
administration device in the third phase of each of the connection
interactions described below and acquired by the onboarding device in
the fourth phase.
9.1. Witness/PIN Authenticated
The witness authenticated, PIN authenticated, and Dynamic QR code
interactions all follow a common interaction pattern.
The Dynamic QR Code (PIN) Authenticated interaction comprises four
phases as follows:
Phase 1: Issue of PIN credential (PIN and Dynamic QR code only) A
PIN code is created and registered with the PIN Registration
interaction described earlier and transmitted to the user by an
out of band communication. In the case of the Dynamic QR code
interaction, this is a QR code that is scanned by the connecting
device.
Phase 2: Onboarding Device Request to Service The onboarding device
creates a RequestConnect message. In the PIN authenticated and
Dynamic QR Code interactions, the RequestConnect is authenticated
by the Device Authentication key and the PIN issued earlier. In
the Witness Authenticated interaction, it is authenticated by the
Device Authentication key alone.
Hallam-Baker Expires 17 April 2025 [Page 61]
Internet-Draft Mesh Protocol Reference October 2024
The onboarding device presents the RequestConnect message to the
service by means of a Connect operation to the service servicing
the account. This results in the exchange of the account and
device profiles and the computation of a witness value from the
two profile fingerprints and two nonce values specified by the
onboarding device and the service. An AcknowledgeConnection
message is posted to the Inbound spool of the account and returned
to the connecting device.
Phase 3: Administration Device Acceptance The account holder
authenticates RequestConnect message and uses an administrative
device to accept or reject the connection request.
If the RequestConnect message has been authenticated by a PIN
code, the connection request can be accepted automatically without
additional user interaction.
Phase 4: Onboarding Device Completion The onboarding device
periodically polls the service for acceptance of the request by
the administration device using the Complete transaction.
The use of the PIN code to authenticate the request message is shown
in $$$$.
The PIN code MAY be presented to the onboarding device in any format
accepted by the device. Administration MAY support presentation of
the account address PIN code as a URI code. Administration devices
SHOULD support presentation of the account address PIN code as a QR
code containing the corresponding URI.
9.1.1. Phase 1:
Alice> meshman account pin /threshold
PIN=ADE7-U5DR-2YNJ-XKVX-4RUE-SVL5-5I
(Expires=2024-10-15T13:10:56Z)
The registration of this PIN value was shown earlier in section $$$
The URI containing the account address and PIN is:
mcd://alice@example.com/ADE7-U5DR-2YNJ-XKVX-4RUE-SVL5-5I
9.1.2. Phase 2:
The onboarding device scans the QR code to obtain the account address
and PIN code. The PIN code is used to authenticate a connection
request:

The service receives the conenct request and authenticates the
message under the device key. The service cannot authenticate the
message under the PIN code because that is not know to the service as
the service cannot decrypt the local spool.
Having authenticated the connect request, the service generates a
random nonce value. The random nonce together with the device and
account profiles are used to calculate the witness value.
The AcknowledgeConnection message is created by the service:

The administration device determines that the device connection
request is authenticated by a PIN code. The PIN code is retrieved
and the message authenticated. This is shown in the PIN registration
interation example in section $$$ above.
Bug: This command is currently showing superflous pending messages
due to the failure to clear messages processed in earlier examples.
The Cataloged device record is created from the public key values
corresponding to the combination of the public keys in the device
profile and those defined by the activation.
This is returned to the onboarding device by wrapping it in a
RespondConnection message posted to the local spool of the account.

9.1.4. Phase 4
The device periodically polls for completion of the connection
request using the Complete transaction.
To provide a final check on the process, the command line tool
presents the UDF of the account profile to which the device has
connected if successful:
Hallam-Baker Expires 17 April 2025 [Page 75]
Internet-Draft Mesh Protocol Reference October 2024
Alice3> meshman device complete
Device UDF = MBQD-CODE-XMWJ-QHE3-2KHZ-UKKF-TVVF
Account = alice@example.com
Account UDF = MBQC-7OHA-RNBA-FRDL-R4GI-YQHA-DL36
Alice3> meshman account sync
The completion request specifies the witness value for the
transaction whose completion is being queried:
{
"CompleteRequest":{
"AccountAddress":"alice@example.com",
"ResponseID":"MDDD-KNM4-KUZH-QVC4-KWLI-5NBW-T54I"}}
The Service responds to the complete request by checking to see if an
entry has been added to the local spool. If so, this contains the
RespondConnection message created by the administration device.
9.2. Preconfigured (Static QR Code)
The preconfigured device connection interaction is used to connect
devices that lack affordances such as a display or a keyboard. It is
also known as the static QR code interaction because a static QR code
printed on the device itself is used to connect it to a user's
account.
*Future*: Note that this interaction is likely to be changed
substantially in future revisions of the specification and the Claim/
PollClaim mechanism removed and replaced with a messaging based
approach.
The interaction has five phases:
Phase 1: Preconfiguration The device to be onboarded is
preconfigured with a ProfileDevice and private key information and
a DeviceDescription posted to a publication service. This process
is typically performed during manufacture. An EARL providing the
ability to locate and decrypt the description is printed on the
device itself as a QR code.
Phase 2: Device description acquisition The administration device
acquiring the onboarding device scans the QR code on the device
and uses this information to obtain the device description by
means of a Claim operation described above as described in the
Device Description.
Phase 3: Administration Device Acceptance This phase is performed in
Hallam-Baker Expires 17 April 2025 [Page 76]
Internet-Draft Mesh Protocol Reference October 2024
the same manner as the Dynamic QR Code (PIN) Authenticated
interaction except that the administration device MAY advise the
device that a connection request is being made by additional means
described in the device description (e.g. WiFi, Bluetooth).
Phase 4: Poll Claim Notification When connected to a network, the
preconfigured device periodically attempts to poll the connection
sources specified to find out if there is a pending request. If a
connection request is posted, the device decrypts it to allow it
to complete the connection process.
Phase 5: Onboarding Device Completion This phase is performed in the
same manner as the Dynamic QR Code (PIN) Authenticated interaction
except that the administration device requires notice that of the
pending connection request.
The main differences between this connection interaction and the
witness/PIN connection interactions are that the device is
preconfigured with the device profile at the time of manufacture and
the onboarding device MAY be acquiring network configuration
information during the connection process.
9.2.1. Phase 1
The manufacturer preconfigures the device
Maker> meshman device preconfig
Device UDF: MBQK-36BF-K7RS-UDWD-PVC3-CVMR-BJCP
File: EBH3-DT6M-G2WA-EF7E-DA42-DN55-7E.medk
This results in the creation of a primary secret which is used to
compute a ProfileDevice and corresponding connection records signed
by the manufacturer's administrator key.
The data is combined to create a DevicePreconfiguration record that
is provisioned to the firmware of the device being preconfigured.

10. Protocol Schema
HTTP Well Known Service Prefix: /.well-known/mmm
Hallam-Baker Expires 17 April 2025 [Page 80]
Internet-Draft Mesh Protocol Reference October 2024
Every Mesh Portal Service transaction consists of exactly one request
followed by exactly one response. Mesh Service transactions MAY
cause modification of the data stored in the Mesh Service or the Mesh
itself but do not cause changes to the connection state. The
protocol itself is thus idempotent. There is no set sequence in
which operations are required to be performed. It is not necessary
to perform a Hello transaction prior to any other transaction.
10.1. Request Messages
A Mesh Portal Service request consists of a payload object that
inherits from the MeshRequest class. When using the HTTP binding,
the request MUST specify the portal DNS address in the HTTP Host
field.
10.1.1. Message: MeshRequest
Base class for all request messages.
[No fields]
10.1.2. Message: MeshRequestUser
Base class for all request messages made by a user.
Inherits: MeshRequest
Account: String (Optional) The fully qualified account name
(including DNS address) to which the request is directed.
Capability: String (Optional) The identifier of the capability under
which access is claimed.
EnvelopedProfileDevice: Enveloped (Optional) Device profile of the
device making the request.
10.2. Response Messages
A Mesh Portal Service response consists of a payload object that
inherits from the MeshResponse class. When using the HTTP binding,
the response SHOULD report the Status response code in the HTTP
response message. However the response code returned in the payload
object MUST always be considered authoritative.
10.2.1. Message: MeshResponse
Base class for all response messages. Contains only the status code
and status description fields.
Hallam-Baker Expires 17 April 2025 [Page 81]
Internet-Draft Mesh Protocol Reference October 2024
[No fields]
10.3. Imported Objects
The Mesh Service protocol makes use of JSON objects defined in the
JOSE Signatgure and Encryption specifications and in the DARE Data At
Rest Encryption extensions to JOSE.
10.4. Common Structures
The following common structures are used in the protocol messages:
10.4.1. Structure: KeyValue

a client to limit the number of records returned, the quantity of
data returned, the earliest and latest data returned, etc.
Store: String (Optional) The container to be searched.
IndexMin: Integer (Optional) Only return objects with an index value
that is equal to or higher than the value specified.
IndexMax: Integer (Optional) Only return objects with an index value
that is equal to or lower than the value specified.
NotBefore: DateTime (Optional) Only data published on or after the
specified time instant is requested.
Before: DateTime (Optional) Only data published before the specified
time instant is requested. This excludes data published at the
specified time instant.

Hallam-Baker Expires 17 April 2025 [Page 82]
Internet-Draft Mesh Protocol Reference October 2024
When a page key is specified, all the other search parameters
except for MaxEntries and MaxBytes are ignored and the service
returns the next set of data responding to the earlier query.
10.4.3. Structure: ConstraintsData
Specifies constraints on the data to be sent.
MaxEntries: Integer (Optional) Maximum number of entries to send.
BytesOffset: Integer (Optional) Specifies an offset to be applied to
