Hi,

Recently I submitted J-PAKE and Schnorr NIZK to IETF for "informational RFC". Both drafts are currently under review in the independent submission stream. 

As per the reviewers' comments, I've revised the drafts to clarify a few points.

Schnorr draft
 * Clarify the parameters for the finite field and elliptic curves. The DSA/ECDSA parameters are used only as an example; other groups can also be used.
 * Clarify the requirement for the hash function. It needs to be collision-resistant in a practical realisation with recommended hash functions given.

J-PAKE draft
 * Clarify that key confirmation can be implicit or explicit, and that explicit key confirmation is recommended in a practical implementation of J-PAKE.

The latest drafts are below:
