Abstract	There have been many proposals in recent years for password-authenticated key exchange protocols, i.e., protocols in which two parties who share only a short secret password perform a key exchange authenticated with the password. However, the only ones that have been proven secured against offline dictionary attacks were based on Diffie–Hellman key exchange. We examine how to design a secure password-authenticated key exchange protocol based on RSA. In this paper, we first look at the OKE and protected-OKE protocols (both RSA-based) and show that they are insecure. Then we show how to modify the OKE protocol to obtain a password-authenticated key exchange protocol that can be proven secure (in the random oracle model). This protocol is very practical; in fact, it requires about the same amount of computation as the Diffie–Hellman-based protocols. Finally, we present an augmented protocol that is resilient to server compromise, meaning (informally) that an attacker who compromises a server would not be able to impersonate a client, at least not without running an offline dictionary attack against that client’s password.
