IETF LAMPS Working Group
The IETF group specifying post-quantum algorithms in X.509 certificates and the Cryptographic Message Syntax.
Why this is listed
Its charter commits it to specifying post-quantum algorithms in PKIX certificates and the Cryptographic Message Syntax, which is normative work rather than guidance about it.
LAMPS, Limited Additional Mechanisms for PKIX and SMIME, is an IETF security area working group maintaining CMP, CMC, EST, S/MIME and PKIX. Its charter commits it to specify the use of post-quantum public key algorithms with PKIX certificates and with the Cryptographic Message Syntax.
The same charter covers hybrid key establishment, with the shared secrets combined using HKDF or a NIST-approved key derivation function; dual signatures pairing a traditional and a post-quantum signature; and streamlined processing for post-quantum certificates, including unsigned X.509 certificates for constrained devices that cannot carry the larger signatures. A question about what a post-quantum certificate looks like on the wire is answered by this group's documents.
