SPAKE2 seems to be the Dual_EC_DRBG of PAKEs (and I'm very surprised the author isn't being accused by a bunch of people on twitter, and some hack tech blogger, of being an NSA plant out to subvert the Internet). There are 2 constant elements used in the calculation and knowledge of the scalar used to generate either of them would allow an attacker to break the exchange. This draft will need to go through a rigorous NUMS procedure in order to populate (the currently empty) section 3, a contentious step that other PAKEs would not need to go through. There are other PAKEs out there so it would be nice to know why SPAKE2 is the one that should be pursued. regards, Dan.
