Abstract. A policy is a statement that an action is permitted or forbidden if certain conditions hold. We introduce a language for reasoning about policies called Rosetta. What mak...
Abstract. Using a probabilistic polynomial-time process calculus designed for specifying security properties as observational equivalences, we develop a form of bisimulation that j...

We study from an implementation viewpoint what constitutes a reasonable and effective notion of structural equivalence of terms in a calculus of concurrent processes and propose op...
Abstract. We present a new elliptic curve cryptosystem with fast encryption and key generation, which is provably secure in the standard model. The scheme uses arithmetic modulo n2...
