At the past SAAG meeting at IETF 111, we had a discussion on approaches for= ensuring post-quantum cryptography (PQC) agility in IETF work [1]. The mi= c-line and jabber generated a robust discussion about PQC and generic prior= ities, but didn't get to discussing specific actions. Also introduced duri= ng that SAAG meeting was a draft "CURDLE-style" (i.e., a scope like the CUR= DLE WG [2]) charter for PQC agility [3]. This charter defined an approach = to fill the gap of adapting or updating IETF protocols, registries, and ass= ociated code points, for which no other WG exists, with PQ cryptographic me= chanisms. Left for discussion was which specific work and partners should = be considered. Since the IETF 111, we've had some mailing list discussion [4] on refining = a proposed approach via [3] and are beginning to define what work might be = a candidate for needing PQC agility but doesn't have a natural, existing WG= . More feedback would be helpful on: (a) Should we be considering an alternative to this kind of "last resort"/"= CURDLE-style" WG? (b) Per the template field "[Post Quantum work collaborators]" in [3], who = should be our partners for PQC guidance? Current suggestions are US NIST a= nd IRTF CFRG. (c) Per the template field "[Protocols requiring attention without an activ= e WG]" in [3], which work should be considered? Current suggestions are se= cure shell (SSH). Previous protocols considered during CURDLE were JOSE, D= NSSEC, XML Digital Signatures and XML Encryption.

It can go as deep as its pa= rticipants and their expertise allows it to go. Although in reality it is m= ore likely to focus on a few areas like CURLE ended up doing.=20 (b) Some of the work the TLS and LAMPS WGs are already doing. For example h= ow PQ KEMs are used in hybrid key exchange in TLS will resemble how key exc= hange takes place in SSH. So I would expect the TLS and LAMPS PQ efforts to= cross pollinate with this WGs efforts.=20 (c) Imo SSH and DNSSEC initially. We ought to get some DNSSEC experts for t= he latter though. For SSH I think there is interest already. JOSE, XML or o= ther orphan standards can be added in the charter if there is more interest= by participants, especially given that there was no documents coming out o= f CURDLE for those.=20 Rgs,=20 Panos -----Original Message----- From: saag On Behalf Of Roman Danyliw Sent: Wednesday, October 20, 2021 4:26 PM To: saag@ietf.org Subject: [EXTERNAL] [saag] Follow-up to IETF 111 discussion on PQC agility CAUTION: This email originated from outside of the organization. Do not cli= ck links or open attachments unless you can confirm the sender and know the= content is safe. Hi! At the past SAAG meeting at IETF 111, we had a discussion on approaches for= ensuring post-quantum cryptography (PQC) agility in IETF work [1]. The mi= c-line and jabber generated a robust discussion about PQC and generic prior= ities, but didn't get to discussing specific actions. Also introduced duri= ng that SAAG meeting was a draft "CURDLE-style" (i.e., a scope like the CUR= DLE WG [2]) charter for PQC agility [3]. This charter defined an approach = to fill the gap of adapting or updating IETF protocols, registries, and ass= ociated code points, for which no other WG exists, with PQ cryptographic me= chanisms. Left for discussion was which specific work and partners should = be considered. Since the IETF 111, we've had some mailing list discussion [4] on refining = a proposed approach via [3] and are beginning to define what work might be = a candidate for needing PQC agility but doesn't have a natural, existing WG= . More feedback would be helpful on: (a) Should we be considering an alternative to this kind of "last resort"/"= CURDLE-style" WG? (b) Per the template field "[Post Quantum work collaborators]" in [3], who = should be our partners for PQC guidance? Current suggestions are US NIST a= nd IRTF CFRG. (c) Per the template field "[Protocols requiring attention without an activ= e WG]" in [3], which work should be considered? Current suggestions are se= cure shell (SSH). Previous protocols considered during CURDLE were JOSE, D= NSSEC, XML Digital Signatures and XML Encryption.
