Recently, Viet et al., \cite{VYT05} have proposed an anonymous
password-authenticated key exchange (PAKE) protocol against a
passive server, who follows the protocol honestly but it is
curious about identity of client. In this paper, we propose an
efficient construction for anonymous PAKE protocol (we call it the
{\sf EAP} protocol) which provides semantic security of session
keys in the random oracle model, with the reduction to the
computational Diffie-Hellman problem, as well as anonymity against
a passive server. Specially, the {\sf EAP} protocol has about
$50\%$ reduction (compared to \cite{VYT05}) in the number of
modular exponentiations for both client and server, and its
communication bandwidth for the modular size of prime $p$ is
independent from the number of clients while \cite{VYT05} is not. |
