Minutes/actions from previous meeting

Minutes from last meeting open as PR Will discuss actions from last meeting in later sections

Updates from related communities

PQCA

• Tooling group still looking for additional members
• Blog post (Linked in) published on PQC in 5G networks (now using mlkem-native)
• Tooling workgroup open to additional contributions - currently working on sonarqube scanning for PQC.
• Note that AWS website now has reference to pq-code-package.

OQS

• No update - no attendees overlap this week
• Noted that mlkem-native adoption into liboqs is in progress

Review of subprojects

mlkem-c-libjade

• No significant update

mlkem-rust-libcrux

• Hoping to get input on issue & discuss in next meeting
• New upstream release (more apis) expected soon (being picked up by Signal)

mlkem-native

• Focussing on liboqs integration.
  • A few minor stumbling blocks.
  • Biggest was some performance regression on x86 not seen in local benchmarks. Fixed and now within 10% of PQCrystals reference implementation.
  • Contributor is that not all the assembly is imported, only that deemed most important for performance, since it causes additional verification burden.
  • Additional verification for ntt/inverse ntt (from John Harrison) for aarch64 readme
  • Integration now ready. Waiting for second approval.
  • Will tag mlkem-native code as beta
  • Work underway to avoid key expansion - will help with NIST API discussion, as well as in performance comparisons (for example as done with OpenSSL)
  • Some CLA discussion - continue in next meeting
  • Background experimentation with AWS-LC especially in relation to toolchain/structure

Open TSC issues

• Changes to meeting times are proposed - please review

Any other business

• Max asked if anyone is looking at ML-DSA key expansion, as there’s been a discussion at the IETF.
  • Primary concern - interoperability.
  • Also finance industry is trying to build tests
  • Discussed Sophie Schmeg’s presentation at the PQCA in December - 20241204(starts 17 minutes in) & mlkem-native discussion on key formats.
