Title:
Security Proofs for an Efficient Password-Based Key Exchange

Authors: Emmanuel Bresson, Olivier Chevassut, David Pointcheval

Abstract:

Password-based key exchange schemes are designed to provide
entities communicating over a public network, and sharing a
(short) password only, with a session key (e.g, the key is used
for data integrity and/or confidentiality). The focus of the
present paper is on the analysis of very efficient schemes that
have been proposed to the IEEE P1363 Standard working group on
password-based authenticated key-exchange methods, but for which
actual security was an open problem. We analyze the AuthA key
exchange scheme and give a complete proof of its security. Our
analysis shows that the AuthA protocol and its multiple modes
of operation are provably secure under the computational
Diffie-Hellman intractability assumption, in both the
random-oracle and the ideal-cipher models.
