Pretty-Simple Password-Authenticated Key-Exchange Under Standard Assumptions

Abstract

In this paper, we propose a pretty-simple password-authenticated key-exchange protocol, which is proven to be secure in the standard model under the following three assumptions. (1) DDH (Decision Diffie-Hellman) problem is hard. (2) The entropy of the password is large enough to avoid on-line exhaustive search (but not necessarily off-line exhaustive search). (3) MAC is selectively unforgeable against partially chosen message attacks, (which is weaker than being existentially unforgeable against chosen message attacks).
