Abstract. One of the central lines of cryptographic research is identifying the weakest assumptions required for the construction of secure primitives. In the context of group sign...
Abstract. We consider compositional properties of reactive systems that are secure in a cryptographic sense. We follow the well-known simulatability approach of modern cryptography...
Abstract. Until recently, the existence of collection of trapdoor permutations (TDP) was believed (and claimed) to imply almost all of the major cryptographic primitives, including...
Abstract. This paper presents a robust software token that was developed to protect user’s digital identity by simple software-only techniques. This work is closely related to Ho...
Abstract. Public-key cryptography is a prerequisite for security in distributed systems and for reliable electronic commerce. The protection of public keys against attacks is the A...
