Re: [Cfrg] PAKE selection process: Maybe we need a modular approach for integrating authentication of human individuals with TLS?

["Stanislav V. Smyshlyaev" <[e-mail]>]

Dear Björn,

Thank you very much!
In my opinion, you’re absolutely right about the importance of these
questions for the process - and, as you may see in the plan of the PAKE
selection process, during the following stages there will be a call for
experts for reviewing the candidate PAKEs regarding such questions as
integrating into TLS and other security protocols, including M2M protocols.

Personally, I believe that your materials will be very helpful for this.
Obviously, it will be important to share your slides on the Stage 4, when
those properties of the nominated PAKEs will be reviewed.

Best regards,
Stanislav
