Secure communication using authenticated channels

Sylvain Pasini

Our main motivation is to design more user-friendly security protocols. Indeed, if the use of the protocol is tedious, most users will not behave correctly and, consequently, security issues occur. An example is the actual behavior of a user in front of an ...

SAS-based Authenticated Key Agreement

Serge Vaudenay, Sylvain Pasini

Key agreement protocols are frequently based on the Diffie-Hellman protocol but require authenticating the protocol messages in two ways. This can be made by a cross-authentication protocol. Such protocols, based on the assumption that a channel which can ...

On the pseudorandomness of top-level schemes of block ciphers

Serge Vaudenay

Block ciphers are usually based on one top-level scheme into which we plug Âround functionsÂ. To analyze security, it is important to study the intrinsic security provided by the top-level scheme from the viewpoint of randomness: given a block cipher in ...
