Abstract. In this paper we revisit one of the most popular passwordbased key exchange protocols, namely the OKE (for Open Key Exchange) scheme, proposed by Luck in 1997. Our result...
We consider the fundamental problem of authenticated group key exchange among n parties within a larger and insecure public network. A number of solutions to this problem have bee...
Typical protocols for password-based authentication assume a single server which stores all the information (e.g., the password) necessary to authenticate a user. Unfortunately, a...

Secure two-party authentication and key exchange are fundamental problems. Traditionally, the parties authenticate each other by means of their identities, using a public-key infr...
TLS is the most important cryptographic protocol in use today. However, up to now there is no complete cryptographic security proof in the standard model, nor in any other model. ...
