A usual concern against physical layer security is that the legitimate parties would need to have (partial) channel state information (CSI) of the eavesdropper in order to design t...

We lift Cardelli, Ghelli and Gordon's secrecy group creation operator [1] to a relative of the spicalculus that supports symmetric key cryptography, and show a natural extens...

We present a powerful and flexible method for automatically checking the secrecy of values inside components. In our framework an attacker may monitor the external communication ...

We consider the General Gaussian Multiple Access Wire-Tap Channel (GGMAC-WT). In this scenario, multiple users communicate with an intended receiver in the presence of an intellige...

We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase...

Equivocation has been widely used as a measure of security after Shannon[10]. For an infinite system such as the wiretap channel defined in [2], equivocation is unbounded and so e...

The standard symbolic, deducibility-based notions of secrecy are in general insufficient from a cryptographic point of view, especially in presence of hash functions. In this paper...

Abstract. Two styles of definitions are usually considered to express that a security protocol preserves the confidentiality of a data s. Reachability-based secrecy means that s sh...

Tagging schemes have been used in security protocols to ensure that the analysis of such protocols can work with messages of bounded length. When the set of nonces is bounded, this...
