Abstract. The recently introduced Galois/Counter Mode (GCM) of operation for block ciphers provides both encryption and message authentication, using universal hashing based on mul...
Abstract-- This paper is concerned with passwordauthenticated key agreement protocols. Designing such protocols represents an interesting challenge since there is no standard way o...
