Abstract

We study client-to-client password-authenticated key exchange (C2C-PAKE) enabling two clients in different realms to agree on a common session key using different passwords. Byun et al. first presented C2C-PAKE schemes under the cross-realm setting. However, the schemes were not formally treated, and subsequently found to be flawed. In addition, in the schemes, there are still rooms for improvements both in computational and communicational aspects. In this paper we suggest an efficient C2C-PAKE (EC2C-PAKE) protocol, and prove that EC2C-PAKE protocol is secure under the decisional Diffie-Hellman assumption in the ideal cipher and random oracle models.
