SSH PQ signatures, DKIM gaps, and LSR energy drafts

IETF lists focused on post-quantum SSH signature adoption, DKIM chain interoperability, and energy-aware IGP state. Parallel threads covered certificate name constraints, deep-space addressing, and a new RTP payload RFC.

SSH WG call for ML-DSA signature draft adoption

The SSH working group ran a call for adoption of hybrid and pure ML-DSA signature drafts. The thread produced 99 messages from 35 participants, including heated exchanges between DJB and the chairs over safety arguments and new AI cryptanalysis. SSH implementers need to track the outcome because it shapes how post-quantum signatures will be standardized in the protocol.

ML-DSA SSH code points held pending draft merge

An IANA request for SSH public key algorithm name code points covering ML-DSA remains on hold until related drafts merge. A Go implementer asked the designated experts to reactivate processing. Assigned code points are required before interoperable post-quantum public-key support can ship in SSH stacks.

DKIM2 interoperability with non-participating nodes

Participants on the ietf-dkim list disputed whether the DKIM2 draft creates an interoperability gap when legacy nodes modify messages and break signature chains. The discussion frames the issue as a protocol problem rather than a matter of local policy. Mail transfer agents and filter authors must understand the expected behavior before deploying DKIM2.

LAMPS feedback on RFC 5280 name constraints

The LAMPS working group examined draft feedback on fixes to RFC 5280 name constraints and wildcard DNS SAN semantics. Twenty-four messages from seven participants explored the proposed changes. PKI and certificate-validation libraries would be directly affected by any clarified matching rules.

LSR adoption discussion for power-group draft

The LSR working group considered adoption of draft-many-lsr-power-group, drawing 41 messages from 16 participants plus cross-WG comments on coordination with the GREEN YANG energy model and the proper scope of IGP state. A concurrent adoption call for revision -03, ending 2026-08-30, examined TE-centric design choices and backwards-compatibility risks. Routing developers evaluating energy-aware extensions should follow whether the work is taken on.

Single versus multiple RIR models for deep-space IPv6

The deepspace list clarified how single-RIR and multiple-RIR models differ in their effect on IPv6 aggregation for proposed space address allocations. Twenty messages from eight participants walked through the aggregation consequences. The distinction matters for any future deep-space addressing architecture that must scale.

RFC 10034 published for V3C RTP payload

The IETF announced RFC 10034, which defines an RTP payload format for Visual Volumetric Video-Based Coding atlas sub-bitstreams. The document supplies the missing mapping needed to carry V3C over RTP. Multimedia and real-time video implementers now have a stable reference for volumetric streams.
