Internet-Draft oauth-dyn-reg November 2012
1. Introduction
In some use-case scenarios, it is desirable or necessary to allow
OAuth clients to obtain authorization from an OAuth authorization
server without the two parties having previously interacted.
Nevertheless, in order for the authorization server to accurately
represent to end-users which client is seeking authorization to
access the end-user's resources, a method for automatic and unique
registration of clients is needed. The OAuth2 authorization
framework does not define how the relationship between the Client and
the Authorization Server is initialized, or how a given client is
assigned a unique Client Identifier. Historically, this has happened
out-of-band from the OAuth protocol. This draft provides a mechanism
for a client to register itself with the Authorization Server, which
can be used to dynamically provision a Client Identifier, and
optionally a Client Secret.
As part of the registration process, this specification also defines
a mechanism for the client to present the Authorization Server with a
set of metadata, such as a display name and icon to be presented to
the user during the authorization step. This draft provides a method
for the client to register and update this information over time.
1.1. Notational Conventions
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].
Unless otherwise noted, all the protocol parameter names and values
are case sensitive.
1.2. Terminology
This specification uses the terms "Access Token", "Refresh Token",
"Authorization Code", "Authorization Grant", "Authorization Server",
"Authorization Endpoint", "Client", "Client Identifier", "Client
Secret", "Protected Resource", "Resource Owner", "Resource Server",
and "Token Endpoint" defined by OAuth 2.0 [RFC6750].
This specification defines the following additional terms:
o Client Registration Endpoint: The OAuth 2.0 Endpoint through which
a Client can request new registration and manage the metadata
associated with it.
o Registration Access Token: An OAuth 2.0 Bearer Token issued by the
Authorization Server through the Client Registration Endpoint
Richer, et al. Expires May 31, 2013 [Page 3]
Internet-Draft oauth-dyn-reg November 2012
which is used by the Client to authenticate itself during update
and secret rotation operations.
1.3. Requirements
[[ Following are proposed requirements for dynamic client
registration. This section is intended for discussion and will
likely be removed in the final draft. ]]
1.3.1. The client needs to be uniquely identifiable by the
authorization server
In order for an authorization server to do proper user-delegated
authorization and prevent unauthorized access it must be able to
identify clients uniquely. As is done today in OAuth, the client
identifier (and optional secret) should thus be issued by the
authorization server and not simply accepted as proposed by the
client.
1.3.2. The authorization server must collect metadata about a client
for later user interaction
In order for the authorization server to describe a client to an end-
user in an authorization step it needs information about the client.
This can be the client name at a minimum, but today servers usually
request at least a description, a homepage URL, and an icon when
doing manual registration.
1.3.3. The authorization server should have the option of strongly
authenticating the client and its metadata
In order to prevent spoofing of clients and enable dynamic building
of strong trust relationships, the authorization server should have
the option to verify the provided information. This might be solved
using message signature verification.
1.3.4. Dynamic client registration must be possible from both web-
server applications and applications with other capabilities and
limitations, such as native applications
Each instance of a native application (that is, the specific instance
running on each device) that is installed and run by the same user
may need the option of getting a unique client identifier. In this
case, there are implications around gathering and displaying enough
information to ensure that the end-user is delegating authorization
to the intended application. The registration protocol should be
simple and flexible enough to allow for multiple types of
applications.
Richer, et al. Expires May 31, 2013 [Page 4]
Internet-Draft oauth-dyn-reg November 2012
1.3.5. Transaction integrity must be ensured
When a client sends information to a server endpoint, it might take
time for this data to propagate through big server installations that
spread across various data centers. Care needs to be taken that
subsequent interactions with the user after the registration process,
such as an authorization request, show the correct data.
2. Client Metadata
Clients generally have an array of metadata associated with their
unique Client Identifier at the Authorization Server. These can
range from human-facing display strings, such as a client name, to
items that impact the security of the protocol, such as the list of
valid redirect URIs.
Extensions and profiles of this specification MAY expand this list,
but MUST at least accept all parameters on this list. The
Authorization Server MUST ignore any additional parameters sent by
the Client that it does not understand.
redirect_uris
REQUIRED A space-delimited list of redirect URIs.
client_name
RECOMMENDED. Human-readable name of the Client to be presented to
the user.
client_url
RECOMMENDED. URL of the homepage of the client. If present, the
server SHOULD display this URL to the end user.
logo_url
OPTIONAL. URL that references a logo for the Client application.
If present, the server SHOULD display this image to the end user
during approval.
contacts
OPTIONAL. Space delimited list of email addresses for people
responsible for this client. The Authorization Server MAY may
these addresses available to end users for support queries. An
Authorization Server MAY use these email addresses as identifiers
for an administrative page for this client.
Richer, et al. Expires May 31, 2013 [Page 5]
Internet-Draft oauth-dyn-reg November 2012
tos_url
OPTIONAL. URL that points to a human-readable Terms of Service
for the Client. The Authorization Server SHOULD display this URL
to the End-User if it is given.
token_endpoint_auth_method
OPTIONAL. The requested authentication type for the Token
Endpoint. Valid values are:
* "none" this is a public client as defined in OAuth 2.0 and does
not have a client secret
* "client_secret_post" the client uses the HTTP POST parameters
defined in OAuth2.0 section 2.3.1
* "client_secret_basic" the client uses HTTP Basic defined in
OAuth 2.0 section 2.3.1
* "client_secret_jwt" the client uses the JWT Assertion profile
with a semetric secret issued by the server
* _private_key_jwt_ the client uses the JWT Assertion profile
with its own private key
Other Authentication methods may be defined by extension. If
unspecified or omitted, the default is "client_secret_basic" HTTP
Basic Authentication Scheme as specified in Section 2.3.1 of OAuth
2.0 [RFC6749].
policy_url
OPTIONAL. A URL location that the Client provides to the End-User
to read about the how the profile data will be used. The
Authorization Server SHOULD display this URL to the End-User if it
is given.
jwk_url
OPTIONAL. URL for the Client's JSON Web Key [JWK] document that
is used for signing Token Endpoint Requests. If
jwk_encryption_url is not provided, the key at jwk_url is also
used as the key to encrypt responses to the Client. If the Client
registers both "x509_url" and "jwk_url", the keys contained in
both formats MUST be the same.
jwk_encryption_url
OPTIONAL. URL for the Client's JSON Web Key [JWK] that is used to
encrypt any responses to the Client. If the Client registers both
"jwk_encryption_url" and "x509_encryption_url", the keys contained
in both formats MUST be the same.
Richer, et al. Expires May 31, 2013 [Page 6]
Internet-Draft oauth-dyn-reg November 2012
x509_url
OPTIONAL. URL for the Client's PEM encoded X.509 Certificate or
Certificate chain that is used for signing Token Endpoint
Requests. If "x509_encryption_url" is not provided, "x509_url" it
is also used to encrypt responses to the Client. If the Client
registers both "x509_url" and "jwk_url", the keys contained in
both formats MUST be the same.
x509_encryption_url
OPTIONAL. URL for the Client's PEM encoded X.509 Certificate or
Certificate chain that is used to encrypt the ID Token and User
Info Endpoint Responses to the Client. If the Client registers
both "jwk_encryption_url" and "x509_encryption_url", the keys
contained in both formats SHOULD be the same.
default_max_age
OPTIONAL. Maximum age of a session in integer seconds. Specifies
that the End-User must be actively authenticated if any present
authentication is older than the specified number of seconds by
default.
default_acr
OPTIONAL. Default Authentication Context class Reference. String
that specifies the default authentication context value that the
Authorization server must use for processing requests from this
client.
3. Client Registration Endpoint
The Client Registration Endpoint is an OAuth 2.0 Endpoint defined in
this document that is designed to allow a Client to register itself
with the Authorization Server. The Client Registration Endpoint MUST
accept HTTP POST messages with request parameters encoded in the
entity body using the "application/x-www-form-urlencoded" format.
The Client Registration Endpoint MUST be protected by a transport-
layer security mechanism when sending requests to the Registration
Endpoint. The server MUST support TLS 1.2 RFC 5246 [RFC5246] and/or
TLS 1.0 [RFC2246] and MAY support additional transport-layer
mechanisms meeting its security requirements. When using TLS, the
Client MUST perform a TLS/SSL server certificate check, per RFC 6125
[RFC6125].
The Endpoint defines three operations that a client can take on it,
switched by the "operation" parameter:
Richer, et al. Expires May 31, 2013 [Page 7]
Internet-Draft oauth-dyn-reg November 2012
o client_register: request that the Authorization Server generate a
new Client Identifier (and optionally a Client Secret) and
associate it with the set of presented metadata (Section 2)
o client_update: update the metadata (Section 2) associated with a
Client Identifier
o rotate_secret: issue a new Registration Access Token and, if
applicable, a Client Secret for a Client
In order to facilitate registered clients updating their information,
the Client Registration Endpoint issues a request_access_token for
clients to securely identify themselves in future connections. As
such, the Endpoint MUST accept requests with OAuth 2.0 Bearer Tokens
[RFC6750] for these operations.
In order to support open registration and facilitate wider
interoperability, the Client Registration Endpoint SHOULD allow
client_register requests with no further authentication. These
requests MAY be rate-limited to prevent a denial-of-service attack on
the Client Registration Endpoint.
In addition, the Client Registration Endpoint MAY accept an initial
authorization credential in the form of an OAuth 2.0 [RFC6749] access
token in order to limit registration to only previously authorized
parties. The method by which this access token is obtained by the
registrant is generally out-of-band and is out of scope of this
specification.
These two aspects, operation selection and client authentication, are
represented by two parameters common to all operations:
operation REQUIRED. Values are "client_register" (for new
registrations), "rotate_secret" to request rotation of the
"client_secret", and "client_update" (for updating parameters of
an existing "client_id").
access_token OPTIONAL. An OAuth2 Bearer token used to access the
Client Registration Endpoint, as defined in OAuth2 Bearer. This
parameter MUST NOT be sent if the Access Token is sent in the HTTP
Authorization header as described in Section 7.1 of OAuth 2.0
[RFC6749]. Access Tokens sent in the authorization header must be
OAuth 2.0 Bearer Tokens [RFC6750].
Each operation takes a different parameter set, and all operations
are described below.
The Client Registration Endpoint MUST ignore all parameters it does
Richer, et al. Expires May 31, 2013 [Page 8]
Internet-Draft oauth-dyn-reg November 2012
not understand.
3.1. Client Registration Request
This operation registers a new client to the Authorization Server.
The Authorization Server assigns this client a unique Client
Identifier, optionally assigns a Client Secret, and associates the
metadata given in the request with the issued Client Identifier. The
request includes the two parameters described above as well as any
parameters described in Client Metadata (Section 2).
operation
REQUIRED. MUST have the value "client_register"
access_token
OPTIONAL. used to restrict new client registration. This
parameter MUST NOT be sent if the Access Token is sent in the HTTP
Authorization header as described in Section 7.1 of OAuth 2.0
[RFC6749]. Access Tokens sent in the authorization header must be
OAuth 2.0 Bearer Tokens [RFC6750].

3.2. Client Registration Response
Upon successful registration, the Client Registration Endpoint
returns the newly-created Client Identifier and, optionally, a Client
Secret. The response also contains a Registration Access Token that
is to be used by the client to perform subsequent operations at this
endpoint, such as client_update and rotate_secret. These items are
returned as a JSON document with the following fields as top-level
members of the root JSON object.
client_id
REQUIRED. The unique Client identifier, MUST NOT be currently
valid for any other registered Client.
client_secret
OPTIONAL. The Client secret. This MUST be unique for each
"client_id". This value is used by confidential clients to
authenticate to the Token Endpoint as described in OAuth 2.0
Section 2.3.1.
registration_access_token
REQUIRED. The Access token to be used by the client to perform
"client_update" and "rotate_secret" requests.
issued_at
OPTIONAL. Specifies the timestamp when the Client Identifier was
issued. The timestamp value MUST be a positive integer. The
value is expressed in the number of seconds since January 1, 1970
00:00:00 GMT.
expires_at
OPTIONAL. The number of seconds from 1970-01-01T0:0:0Z as
measured in UTC that the "client_secret" will expire or "0" if
they do not expire. See RFC 3339 [RFC3339] for details regarding

"expires_at":2893276800
}
3.3. Client Update Request
This operation updates a previously-registered client with new
metadata at the Authorization Server. This request MUST be protected
by the Registration Authorization Token associated with the Client.
This request MAY include any fields described in Client Metadata
(Section 2). The values of Client Metadata fields in this request
MUST replace (not augment) the values previously associated with this
Client. Empty values in Client Metadata MUST be taken as a request
to clear any existing value of that field.
operation
REQUIRED, MUST have the value "client_update"

3.4. Client Update Response
Upon successful update, the Client Registration Endpoint returns a
JSON document with the following fields as top-level members of the
root JSON object.
client_id
REQUIRED. The unique Client identifier, MUST equal the value of
the client_id returned in the original client_register request.
Following is a non-normative example response:
HTTP/1.1 200 OK
Content-Type: application/json
Cache-Control: no-store
{
"client_id":"s6BhdRkqt3",
}
[[ Editor's note: should this return the entire client data object,
for confirmation and review, including any fields that may have been
asserted by the AS? ]]
3.5. Rotate Secret Request
This operation allows the client to rotate its current Registration
Access Token as well as its Client Secret, if it has one.
Richer, et al. Expires May 31, 2013 [Page 12]
Internet-Draft oauth-dyn-reg November 2012
operation REQUIRED. MUST have the value rotate_secret
access_token REQUIRED. The Registration Access Token that was
issued during the client_register step, or previous client_update
or rotate_secret calls. This parameter MUST NOT be sent if the
Access Token is sent in the HTTP Authorization header as described
in Section 7.1 of OAuth 2.0 [RFC6749]. Access Tokens sent in the
authorization header must be OAuth 2.0 Bearer Tokens [RFC6750].
Following is a non-normative example request (with line wraps for
display purposes only):
POST /register HTTP/1.1
Accept: application/x-www-form-urlencoded
Host: server.example.com
Authorization: Bearer reg-23410913-abewfq.123483
operation=rotate_secret
3.6. Rotate Secret Response
Upon successful rotation of the Registration Access Token and
optionally the Client Secret, the Client Registration Endpoint
returns a JSON document with the following fields as top-level
members of the root JSON object.
client_id
REQUIRED. The unique Client identifier, MUST match the client_id
issued in the original client_register request.
client_secret
REQUIRED if the server initially issued this Client a Client
Secret, otherwise the server MUST NOT return a value. The value
MUST be unique for each "client_id".
registration_access_token
REQUIRED The Access token to be used by the client to perform
subsequent "client_update" and "rotate_secret" requests.
issued_at
OPTIONAL. Specifies the timestamp when the identifier was issued.
The timestamp value MUST be a positive integer. The value is
expressed in the number of seconds since January 1, 1970 00:00:00
GMT.
expires_at
OPTIONAL. The number of seconds from 1970-01-01T0:0:0Z as
measured in UTC that the "client_secret" will expire or "0" if
they do not expire. See RFC 3339 [RFC3339] for details regarding

date/times in general and UTC in particular.
Following is a non-normative example response:
HTTP/1.1 200 OK
Content-Type: application/json
Cache-Control: no-store
{
"client_id":"s6BhdRkqt3",
"client_secret":
"cf136dc3c1fd9153029bb9c6cc9ecead918bad9887fce6c93f31185e5885805d",
"registration_access_token": "this.is.a.access.token.value.ffx83",
"expires_at":2893276800
}
The Authorization Server SHOULD discard and invalidate the Request
Access Token and the Client Secret associated with this Client after
successful completion of this request.
3.7. Client Registration Error Response
When an OAuth error condition occurs, the Client Registration
Endpoint returns an Error Response as defined in Section 5.2 of the
OAuth 2.0 specification.
When a registration error condition occurs, the Client Registration
Endpoint returns a HTTP 400 status code including a JSON object
describing the error in the response body.
The JSON object contains two members:
error
The error code, a single ASCII string.
error_description
The additional text description of the error for debugging.
This specification defines the following error codes:
invalid_operation
The value of "operation" is invalid or not supported.
invalid_redirect_uri
The value of one or more "redirect_uris" is invalid.
Richer, et al. Expires May 31, 2013 [Page 14]
Internet-Draft oauth-dyn-reg November 2012
invalid_client_metadata
The value of one of the client metadata (Section 2) fields is
invalid.
Following is a non-normative example of an error response (with line
wraps for display purposes only):
HTTP/1.1 400 Bad Request
Content-Type: application/json
Cache-Control: no-store
{
"error":"invalid_operation",
"error_description":"The value of the operation parameter must
be one of client_register, rotate_secret or client_update."
}
4. IANA Considerations
This document makes no requests of IANA.
5. Security Considerations
[[ Editor's note: Following are some security considerations taken
whole from the UMA and OpenID Connect source drafts. ]]
Since requests to the Client Registration Endpoint result in the
transmission of clear-text credentials (in the HTTP request and
response), the server MUST require the use of a transport-layer
security mechanism when sending requests to the Registration
Endpoint. The server MUST support TLS 1.2 RFC 5246 [RFC5246] and/or
TLS 1.0 [RFC2246] and MAY support additional transport-layer
mechanisms meeting its security requirements. When using TLS, the
Client MUST perform a TLS/SSL server certificate check, per RFC 6125
[RFC6125].
As this endpoint is an OAuth2 Protected Resource, requests to the
Registration Endpoint SHOULD have some rate limiting on failures to
prevent the Registration Access Token from being disclosed though
repeated access attempts.
The authorization server MUST treat all client metadata as self-
asserted. A rogue Client might use the name and logo for the
legitimate Client, which it is trying to impersonate. An
Authorization Server needs to take steps to mitigate this phishing
risk, since the logo could confuse users into thinking they're
logging in to the legitimate Client. For instance, an Authorization
Richer, et al. Expires May 31, 2013 [Page 15]
Internet-Draft oauth-dyn-reg November 2012
Server could warn if the domain/site of the logo doesn't match the
domain/site of redirect URIs. An Authorization Server can also make
warnings against untrusted Clients in all cases, especially if
they're dynamically registered, have not been trusted by any users at
the Authorization Server before.
In a situation where the Authorization Server is supporting open
Client registration, it must be extremely careful with any URL
provided by the Client that will be displayed to the user (e.g.
"logo_url" and "policy_url"). A rogue Client could specify a
registration request with a reference to a drive-by download in the
"policy_url". The Authorization Server should check to see if the
"logo_url" and "policy_url" have the same host as the hosts defined
in the array of "redirect_uris".
While the Client Secret can expire, the Registration Access Token
should not expire while a client is still actively registered. If
this token were to expire, a Client could be left in a situation
where it has no means of updating itself and must register itself
anew. As the Registration Access Tokens are long-term credentials,
they MUST be protected by the Client as a secret. [[ Editor's note:
with the right error codes returned from client_update, the AS could
force the Client to call rotate_secret before going forward,
lessening the window for abuse of a leaked registration token. ]]
