ENHANCED VERIFIER-BASED PASSWORD AUTHENTICATED KEY AGREEMENT PROTOCOL FOR THREE-PARTIES
Department of Electronics, Communications and Computers Engineering, Faculty of Engineering at Helwan, Helwan University.
Abstract
Most of password authenticated key agreement protocols have focused on the two-party setting where two communicating parties share a password. However, in the two-party setting any user may want to communicate with other users who have not shared the same password. In this paper we present an efficient verifier-based password authenticated key agreement protocol for three-parties. In the three-party setting each user only shares a password with a trusted server which authenticates two users and helps the users with different passwords share a common session key. Our proposed protocol is secure against several attacks and provides perfect forward secrecy.
