I had to … [Ballot comment] These comments can be addressed or ignored as seen fit by the authors "TLS Exporters" is mentioned with no reference. I had to google it to find RFC 5705. Maybe just add the reference here and add it as informative reference? Each of these derived PSKs are bound a target missing "to " i.e., not from a TLS connection, which is a tuple of [...] I would use: (i.e., not from a TLS connection) to make it clear that the "tuple" is not related to that part of the sentence. If the EPSK is a key derived from some other protocol [...] Why 'other' ? As opposed to? TLS 1.3 ? Even if derived from some external TLS 1.3 protocol, wouldn't everything here still apply? That is, an EPSK is per definition derived from "something external" and that would need a proper context identifier for channel binding. "Since the EPSK is a key derived from an external protocol, [...]" Note that this means future versions of TLS will increase the number of PSKs derived from an external PSK. The number of PSKs? I think what is meant is the number of labels corresponding to target_protocol ? But also, would it not only increase if one would be willing to still support the older TLS versions? e.g. if we get to TLS 1.5, we might no longer need to derive the PSK for TLS 1.3, because we won't want to speak that old protocol anymore. Future specifications that change the way the KDF is negotiated will need to update this specification to make clear how target KDFs are determined for the import process. Doesn't this statement technically cause an Update: 8446 As in, someone writing TLS 1.4 needs to be aware of this and the way to do this is to make this document Update: 8446 ? that means Application-Layer Protocol Negotiation value [...] I had to reread this a few times. I suggest: this means that the Application-Layer Protocol Negotiation value [...] If a client or server wish to wish -> wishes External PSK identities are typically static by design so that endpoints may use them to lookup keying material. However, for some systems and use cases, this identity may become a persistent tracking identifier. One could use ephemeral identities to make it harder to track users. It would still be a static lookup table, just much larger. Or if one really cares, a onetime pad could be used to provide ephemeral identities per client. |

Section 3, "Each of these derived PSKs are bound a target protocol," should be "bound *to* a target". (Looks like Erik Kline noted this in -06 as well.) 2. Section 6, "However, only limited analysis has been done, and as such is not a recommended configuration." As such, *what* is not? Probably "this is not" would be an adequate fix. 3. Section 8, " External PSK identities are typically static by design so that endpoints may use them to lookup keying material." My preference would be "look up" and not "lookup". |

The -07 draft addressed all of the DISCUSS and COMMENT feedback from the 01/07/2021 telechat. However, I had not noticed that since 14 months had passed since telechat, this document lost the needed quorum of ballots from the IESG -- it's short two. It should not have been advanced of out IESG Evaluation. The document has been put back on the April 2022 telechat. |

IIUC ImportedIdentity has a maximum length of 2^17 + 2. But the Identity field in the PSK option has a maximum length of 2^16-1. I presume this never actually happens, but the spec should handle the boundary condition, perhaps by limiting the first two fields of Imported Identity to sum to 2^16-5 bytes or something. - It says 'Endpoints SHOULD generate a compatible "ipskx" for each target ciphersuite they offer.' but then the example shows two ciphers that equire only one derived key. Do you mean "hash algorithm" instead of "ciphersuite"? TLS_AES_128_GCM_SHA256 and TLS_CHACHA20_POLY1305_SHA256 are different ciphersuites according to RFC 8446. |

I specifically call out the note in Section 4.1 about which HKDF-Expand-Label is to be used, since that would affect the actual derived keys for DTLS 1.3 (and any hypothetical future TLS versions). Section 1 While there is no known way in which the same external PSK might produce related output in TLS 1.3 and prior versions, only limited analysis has been done. Applications SHOULD provision separate PSKs for TLS 1.3 and prior versions. To mitigate against any interference, this document specifies a PSK Importer interface by which external PSKs may be imported and subsequently bound to a specific key derivation function (KDF) and hash function for use in TLS 1.3 [RFC8446] and DTLS 1.3 [DTLS13]. [...] IIRC the main target use cases for this mechanism are for *existing* external PSKs (violating the "SHOULD" from the first quoted paragraph), as well as deployments that are simplified by only needing to provision a single PSK. Does it make sense to include such clarifying description here? (Similarly, is it accurate to say that "[a]pplications SHOULD provision separate PSKs [...], but the mechanism defined in this document provides a partial mitigation for use when that is not possible"? Also, we only use the word "interference" twice in this document (this is the first instance), so it might be worth a couple more words to clarify the nature of the potential interference. Section 3 non-imported keys for TLS versions prior to TLS 1.3. Non-imported and imported PSKs are distinct since their identities are different on the wire. See Section 6 for more details. (side note?) I think the precise story here is a little subtle -- for any given key, the imported and non-imported identities are distinct, but in principle one could construct a non-imported identity that overlaps with an imported identity for a different key (and we say as much at the end of Section 7). This is vanishingly rare to happen by chance, but makes the statement as written not quite categorically true. That said, the change to the binder key derivation (§ 4.2) seems to obviate any potential consequences to such a collision (though the connection attempt would presumably fail). Endpoints which import external keys MUST NOT use either the external keys or the derived keys for any other purpose. Moreover, each IIUC, this is "MUST NOT use the keys that are input to the import process for any purpose other than the importer, and MUST NOT use the derived keys for any purpose other than TLS PSKs". Is it worth spelling it out explicitly like that? external PSK MUST be associated with at most one hash function, as per the rules in Section 4.2.11 from [RFC8446]. See Section 7 for more discussion. Does this requirement apply to the inputs to the importer process, the outputs, or both? Section 3.1 * Imported PSK (IPSK): A PSK derived from an EPSK, External Identity, optional context string, target protocol, and target KDF. There is an "External Identity" that is contained within the EPSK itself; is the "External Identity" listed here distinct from that? Section 4.1 The PSK Importer interface takes as input an EPSK with External Identity "external_identity" and base key "epsk", as defined in Section 3.1, along with an optional context, and transforms it into a set of PSKs and imported identities for use in a connection based on target protocols and KDFs. In particular, for each supported target protocol "target_protocol" and KDF "target_kdf", the importer constructs an ImportedIdentity structure as follows: If I understand correctly the "target_kdf" is supposed to be the KDF associated with the cipher suite(s) the derived PSK will be usable for. This is something of a divergence from RFC 8446, where we *assume* that the KDF will be HKDF and associate only a *hash function* with the cipher suite. While discussing a more generic KDF concept seems reasonable (and is directly in line with the cryptographic principles that motivate this work), I'd recommend adding a few more words somewhere in this section to clarify the relationship between the target_kdf and the cipher suite(s), probably in the paragraph that starts "[e]ndpoints SHOULD generate a compatible 'ipskx' for each target ciphersuite they offer". struct { opaque external_identity<1...2^16-1>; opaque context<0..2^16-1>; uint16 target_protocol; uint16 target_kdf; } ImportedIdentity; Should we say that this is using the TLS presentation language? ImportedIdentity.context MUST include the context used to derive the EPSK, if any exists. For example, ImportedIdentity.context may (nit?) "derive" suggests a cryptographic key derivation process, but the rest of the prose suggests that this is more a process of "identification" or "determination". Is there a more appropriate word to use? Given an ImportedIdentity and corresponding EPSK with base key "epsk", an Imported PSK IPSK with base key "ipskx" is computed as follows: epskx = HKDF-Extract(0, epsk) ipskx = HKDF-Expand-Label(epskx, "derived psk", Hash(ImportedIdentity), L) I think we need to say that the HKDF-Expand-Label used (i.e., the HkdfLabel.label prefix) is the one corresponding to ImportedIdentity.target_protocol. L corresponds to the KDF output length of ImportedIdentity.target_kdf as defined in Section 9. For hash-based KDFs, such as HKDF_SHA256(0x0001), this is the length of the hash function output, i.e., 32 octets. This is required for the IPSK to be of length (32 octets for SHA256, not all hash-based KDFs) The identity of "ipskx" as sent on the wire is ImportedIdentity, i.e., the serialized content of ImportedIdentity is used as the content of PskIdentity.identity in the PSK extension. The corresponding TLS 1.3 binder key is "ipskx". In RFC 8446, the "binder_key" is the *output* of the key schedule, but ipskx is an *input* to the key schedule. So I think we want to say something like "the corresponding PSK input for the TLS 1.3 key schedule is 'ipskx'". The hash function used for HKDF [RFC5869] is that which is associated with the EPSK. It is not the hash function associated with ImportedIdentity.target_kdf. If no hash function is specified, I predict that someone will mess up the hash function selection while implementing this. Perhaps we could provide test vectors for the full matrix of (EPSK Hash, target_kdf hash) pairs using SHA256/SHA384? SHA-256 [SHA2] MUST be used. Diversifying EPSK by I think we might be able to tolerate the *protocol* having a strict requirement that the associated hash function is specified, and provide a recommended value that would be used by people deploying the protocol in the absence of other information. This might in some sense help future-proof the document for the scenario where SHA256 weakens or is broken and the default should change. KDFs, protocols, and context string(s) are known a priori. EPSKs MAY also be imported for early data use if they are bound to protocol settings and configurations that would otherwise be required for early data with normal (ticket-based PSK) resumption. Minimally, that means Application-Layer Protocol Negotiation [RFC7301], QUIC RFC 8446 does not limit 0-RTT data to resumption, so I think we just want "if they are bound to the protocol settings and configuration that are required for sending early data". Also, nit: I think we usually refer to the "ALPN value" instead of just "ALPN" being configured. Section 5 If a client or server wish to deprecate a hash function and no longer use it for TLS 1.3, they remove the corresponding KDF from the set of target KDFs used for importing keys. This does not affect the KDF operation used to derive Imported PSKs. Should we also include a paragraph about how to deprecate the Hash used in deriving Imported PSKs? (It's fixed per EPSK, so, "configure a new EPSK", basically.) Section 6 Recall that TLS 1.2 permits computing the TLS PRF with any hash algorithm and PSK. Thus, an EPSK may be used with the same KDF (and underlying HMAC hash algorithm) as TLS 1.3 with importers. However, critically, the derived PSK will not be the same since the importer differentiates the PSK via the identity and target KDF and protocol. Thus, PSKs imported for TLS 1.3 are distinct from those used in TLS 1.2, and thereby avoid cross-protocol collisions. [...] As I read this I recalled that up in Section 1 we say that applications "SHOULD provision separate PSKs for TLS 1.3 and prior versions". The scenario being described here sounds like it can only occur if that SHOULD is ignored, which might be worth reiterating. We also say in § 4.1 that "external PSKs MUST NOT be imported for (D)TLS 1.2 or prior versions". In light of these two observations, my best interpretation of the quoted text is that it should be equivalent to: NEW: Recall that TLS 1.2 permits computing the TLS PRF with any hash algorithm and PSK. Accordingly, a given EPSK might be both used directly as a TLS 1.2 PSK and used with TLS 1.3 via the importer mechanism (noting that this configuration is not recommended, per Section 1), using the same KDF algorithm. However, because the TLS 1.3 importer mechanism includes an additional key-derivation step, the actual PSK used in the TLS 1.3 key schedule will be distinct from the one used in the TLS 1.2 key schedule, so there are no cross-protocol collisions possible. -- Note that this does not preclude endpoints from using non-imported PSKs for TLS 1.2. For some reason this line implies to me that endpoints might use imported PSKs for TLS 1.2, but this is forbidden by Section 4.1 (as quoted above). Perhaps "does not preclude endpoints from continuing to use TLS 1.2 and the non-imported PSKs it requires"? Section 7 We should probably note that any information placed in ImportedIdentity.context will be visible on the wire in cleartext, and thus that confidential identifiers from other protocols should either not be used or should be protected (e.g., by hashing) prior to use. 1. Externally provisioned PSKs imported into a TLS connection achieve compound authentication of the provisioning process and connection. 2. Context-free PSKs only achieve authentication within the context of a single connection. Do we need to use psk_dh_ke to get the strong compound authentication property, or is it attainable with psk_ke as well? Section 10.1 I'm not sure why [QUIC] and RFC 5246 are listed as normative references. Appendix B The Selfie attack [Selfie] relies on a misuse of the PSK interface. The PSK interface makes the implicit assumption that each PSK is known only to one client and one server. If multiple clients or multiple servers with distinct roles share a PSK, TLS only authenticates the entire group. A node successfully authenticates its peer as being in the group whether the peer is another node or itself. I think it may be useful to call out that the "multiple clients" and "multiple servers" case can occur even when there are only two endpoints that know the key (that is, when they do not have predetermined client/server roles). struct { opaque client_mac<0..2^16-1>; opaque server_mac<0..2^16-1>; } Context; We may not need the whole 16k to hold a MAC address, especially since this is just an example. If an attacker then redirects a ClientHello intended for one node to a different node, the receiver will compute a different context string and the handshake will not complete. Similarly to the above, this could be "a different node (including the node that generated the ClientHello)". |

The example seems to show "imp binder" perhaps concatenated with the "standard" sequence, rather than "imp binder" /replacing/ "ext binder". Am I way off base here? In other words, should "ext binder" | "res binder" | "imp binder" actually be (if I understand the use of the word "replace" correctly): "imp binder" | "res binder" ?

05 | Sabrina Tanamal | (Via drafts-lastcall@iana.org): IESG/Authors/WG Chairs: The IANA Functions Operator has completed its review of draft-ietf-tls-external-psk-importer-05. If any part of this review is inaccurate, please let … (Via drafts-lastcall@iana.org): IESG/Authors/WG Chairs: The IANA Functions Operator has completed its review of draft-ietf-tls-external-psk-importer-05. If any part of this review is inaccurate, please let us know. The IANA Functions Operator understands that, upon approval of this document, there is a single action which we must complete. A new registry is to be created called the TLS KDF Identifiers registry. The new registry will be located on the Transport Layer Security (TLS) Parameters registry page located at: https://www.iana.org/assignments/tls-parameters/ The new registry will have values in the range 0x0000-0xffff. Values in the range 0x0000-0xfeff are assigned via Specification Required as defined in RFC8126. Values in the range 0xff00-0xffff are reserved for Private Use. There are initial registrations in the new registry as follows: +-----------------+--------+---------------+ | KDF Description | Value | Reference | +=================+========+---------------+ | Reserved | 0x0000 | [ RFC-to-be ] | +-----------------+--------+---------------+ | HKDF_SHA256 | 0x0001 | [ RFC-to-be ] | +-----------------+--------+---------------+ | HKDF_SHA384 | 0x0002 | [ RFC-to-be ] | +-----------------+--------+---------------+ | Unassigned | 0x0003-| | | | 0xffff-| | +-----------------+--------+---------------+ The IANA Functions Operator understands that this is the only action required to be completed upon approval of this document. Note: The actions requested in this document will not be completed until the document has been approved for publication as an RFC. This message is meant only to confirm the list of actions that will be performed. Thank you, Sabrina Tanamal Senior IANA Services Specialist |

05 | Joseph Salowey | As required by RFC 4858, this is the current template for the Document Shepherd Write-Up. Changes are expected over time. This version is dated … As required by RFC 4858, this is the current template for the Document Shepherd Write-Up. Changes are expected over time. This version is dated 1 November 2019. (1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header? This document is a Standards Track Document. It is a improvement to the external PSK mechanism for TLS. The document type is indicated in the page header. (2) The IESG approval announcement includes a Document Announcement Write-Up. Please provide such a Document Announcement Write-Up. Recent examples can be found in the "Action" announcements for approved documents. The approval announcement contains the following sections: Technical Summary: This document describes an interface for importing external Pre-Shared Keys (PSKs) into TLS 1.3. Working Group Summary: Since this document addresses some potential security issues in TLS 1.3 there was a fair amount of discussion in the working group. At this point there is good consensus for the document within the working group. Document Quality: There are implementations of the protocol and a number of implementers have shown interest. The document has had review in the context of the "selfie" attack which it helps to address. Personnel: Document Shepherd is Joe Salowey. Responsible Area Director is Ben Kaduk (3) Briefly describe the review of this document that was performed by the Document Shepherd. If this version of the document is not ready for publication, please explain why the document is being forwarded to the IESG. The Document Shepherd has reviewed the document and believes it is ready for publication. (4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? No. (5) Do portions of the document need review from a particular or from broader perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or internationalization? If so, describe the review that took place. No. (6) Describe any specific concerns or issues that the Document Shepherd has with this document that the Responsible Area Director and/or the IESG should be aware of? For example, perhaps he or she is uncomfortable with certain parts of the document, or has concerns whether there really is a need for it. In any event, if the WG has discussed those issues and has indicated that it still wishes to advance the document, detail those concerns here. The Shepherd has no concerns and believes the document is in good shape and addresses a need in the industry. (7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why? Yes. (8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. No disclosure has been filed. (9) How solid is the WG consensus behind this document? Does it represent the strong concurrence of a few individuals, with others being silent, or does the WG as a whole understand and agree with it? The document has strong consensus from the working group. (10) Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarise the areas of conflict in separate email messages to the Responsible Area Director. (It should be in a separate email because this questionnaire is publicly available.) No (11) Identify any ID nits the Document Shepherd has found in this document. (See http://www.ietf.org/tools/idnits/ and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough. No Nits. (12) Describe how the document meets any required formal review criteria, such as the MIB Doctor, YANG Doctor, media type, and URI type reviews. NA (13) Have all references within this document been identified as either normative or informative? Yes (14) Are there normative references to documents that are not ready for advancement or are otherwise in an unclear state? If such normative references exist, what is the plan for their completion? No (15) Are there downward normative references references (see RFC 3967)? If so, list these downward references to support the Area Director in the Last Call procedure. DownRefs to rfc5869 - HMAC (16) Will publication of this document change the status of any existing RFCs? Are those RFCs listed on the title page header, listed in the abstract, and discussed in the introduction? If the RFCs are not listed in the Abstract and Introduction, explain why, and point to the part of the document where the relationship of this document to the other RFCs is discussed. If this information is not in the document, explain why the WG considers it unnecessary. No (17) Describe the Document Shepherd's review of the IANA considerations section, especially with regard to its consistency with the body of the document. Confirm that all protocol extensions that the document makes are associated with the appropriate reservations in IANA registries. Confirm that any referenced IANA registries have been clearly identified. Confirm that newly created IANA registries include a detailed specification of the initial contents for the registry, that allocations procedures for future registrations are defined, and a reasonable name for the new registry has been suggested (see RFC 8126). The Document Shepherd has reviewed the IANA considerations to make sure they are accurate and clear. The registry names are clearly identified along with initial content and allocation procedures. (18) List any new IANA registries that require Expert Review for future allocations. Provide any public guidance that the IESG would find useful in selecting the IANA Experts for these new registries. "TLS KDF Identifiers" is a new registry. The group of experts should use the existing TLS Experts group (19) Describe reviews and automated checks performed by the Document Shepherd to validate sections of the document written in a formal language, such as XML code, BNF rules, MIB definitions, YANG modules, etc. NA (20) If the document contains a YANG module, has the module been checked with any of the recommended validation tools (https://trac.ietf.org/trac/ops/wiki/yang-review-tools) for syntax and formatting validation? If there are any resulting errors or warnings, what is the justification for not fixing them at this time? Does the YANG module comply with the Network Management Datastore Architecture (NMDA) as specified in RFC8342? NA |
