Dear CFRG,

we would like to start a broader review of the current CPace draft-irtf-cfrg-cpace-03 before Christmas and would welcome any feedback on the draft's current version.

We would be happy if we could integrate your opinions and feedback already before the next larger review round as to lower the number of cycles that we will need for getting the draft in a good shape.

Best regards,

Björn

(on behalf of all authors.)

P.S.:

FYI: The slides and the talk regarding the latest CPace security analysis paper at asiacrypt is now also openly available online https://asiacrypt.iacr.org/2021/program.php.

Betreff: Re: [CFRG] I-D Action: draft-irtf-cfrg-cpace-03.txt

Dear CFRG,

the cpace draft did undergo some major restructuring lately, and we 
incorporated the latest findings from the security analyses in [1],[2]. 
We would appreciate a review by CFRG at this point.

In particular, we were asking ourselves the following questions:

- Is the “object” notation for hash function and group environment clear?

- Should we explicitly consider both initiator/responder + parallel 
version or only focus on one setting for conciseness?

- What is the best way for prepending field lengths to octet strings? 
(Current suggestion: UTF8)

- Overall length: is it too long? Any suggestions for shortening?

Best,
Julia (on behalf of all authors)
