Strong security notions often introduce strong constraints on the construction of cryptographic schemes: semantic security implies probabilistic encryption, while the resistance to...
Abstract. It has recently been shown that logic circuits in the implementation of cryptographic algorithms, although protected by “secure” random masking schemes, leak side-cha...
Traditional password-based authentication and key-exchange protocols suffer from the simple fact that a single server stores the sensitive user password. In practice, when such a ...
Abstract. We propose and realize a definition of security for passwordbased key exchange within the framework of universally composable (UC) security, thus providing security guar...

The prevalent use of the signature-based approach in modern intrusion detection systems (IDS) emphasizes the importance of the efficient management of the employed signature sets....
