Enhanced password-based key establishment protocol
Abstract
In this paper we analyse a password-based authenticated key establishment protocol due to Laih, Ding and Huang, which enables a user to authenticate himself to a server and negotiate a shared session key. This protocol is also designed to guarantee that a human being is actually involved in an ongoing protocol execution. However we show that the protocol suffers from offline dictionary attacks. We propose an enhanced password-based authenticated key establishment protocol which is secure against offline dictionary attacks, and that possesses an additional feature guaranteeing that a user is involved in each protocol execution.
