[saag] CFRG report for IETF 124

CFRG met twice this week: on Monday and on Thursday. Many existing and 
proposed documents were discussed. Some highlights:

1) Editors of CPace think that it is done and ready for progression 
towards RFC.

2) Verifiable Distributed Aggregation Functions (VDAF) is close to RGLC, 
but suggesting to incorporate some optimizations for range proofs over 
nonpowers of 2, and converting things into a Lagrange basis to 
accelerate proofs.

3) The "Pairing-friendly curves" document is being resurrected. Several 
documents depend on it (including in IETF). We are likely to have an 
interim meeting in early 2026 to progress it and related documents.

4) Hybrid KEM documents are progressing nicely and are nearly ready for 
Crypto Panel review.

5) We had an update on a pair of recently adopted drafts on Sigma 
protocols and Fiat-Shamir.

6) There was an update on Longfellow ZK.

7) We also had a couple of presentations on Hybrid Digital Signatures.


Best Regards,

Alexey
