Re: [TLS] TLS-PWD vs. TLS-SRP

Dear all,

These are clarifying questions because TLS WG is going with PWD towards
"standard RFC" though PWD has no provable security and is less efficient
(compared to SPEKE and AugPAKE).
Are all tls wg members already clarified with advantages of using tls-pwd?
If so, just let me know.

For patent issues between SPEKE and PWD, there was no conclusions in the
earlier IPsec meetings to my understanding.

Best regards,
Shin
