A number of key establishment protocols claim the property of forward secrecy, where the compromise of a longterm key does not result in the compromise of previously computed sess...
Sensor networks are composed of a large number of low power sensor devices. For secure communication among sensors, secret keys must be established between them. The establishment...
In this paper we study the link between formal and cryptographic models for security protocols in the presence of a passive adversary. In contrast to other works, we do not conside...
We introduce the notion of hierarchical group signatures. This is a proper generalization of group signatures, which allows multiple group managers organized in a tree with the si...
Abstract. We propose a one-round 1-out-of-n computationally-private information retrieval protocol for -bit strings with low-degree polylogarithmic receivercomputation, linear send...
