We study a security property for processes in dynamic contexts, i.e., contexts that can be reconfigured at runtime. The security property that we propose in this paper, named Per...
We propose a new real-time authentication scheme for memory. As in previous proposals the scheme uses a Merkle tree to guarantee dynamic protection of memory. We use the universal...
Routing is a critical function in multi-hop mobile ad hoc networks (MANETs). A number of MANET-oriented routing protocols have been proposed, of which DSR is widely considered bot...
Abstract. We re-visit the problem of perfectly secure message transmission (PSMT) in a directed network under the presence of a threshold adaptive Byzantine adversary, having unbou...
In this paper we present the first public key encryption scheme that is structure preserving, i.e., our encryption scheme uses only algebraic operations. In particular it does not...
