Abstract

In this paper, we propose a S/KEY based authentication protocol using smart cards to address the vulnerabilities of both the S/KEY authentication protocol and the secure one-time password protocol which YEH, SHEN and HWANG proposed [1]. Because our protocol is based on public key, it can authenticate the server and distribute a session key without any pre-shared secret. Also, it can prevent off-line dictionary attacks by using the randomly generated user secret that is stored in the users smart card. More importantly, it can truly achieve the strength of the S/KEY scheme that no secret information need be stored on the server.
