Abstract

This paper proposes an efficient password authenticated key agreement scheme for multi-server architecture. The proposed scheme allows user to access multi-server securely by keeping one weak password and a smart card only. The client user and server will authenticate each other and agree a secret common session key for each request in the ending of the proposed scheme. The proposed scheme is based on Chang & Lee's scheme proposed in 2004 but is more efficient and more user-friendly than the previous results.
