We define a new notion of relatively-sound non-interactive zeroknowledge (NIZK) proofs, where a private verifier with access to a trapdoor continues to be sound even when the Ad...
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. Proof-carrying code (PCC) allows a code producer to associate to a program a machine-checkable proof of its safety. In the original approach to PCC, the safety policy inc...
Abstract. We study the link between formal and cryptographic models for security protocols in the presence of passive and adaptive adversaries. We first describe the seminal resul...
This paper presents the first type system for statically analyzing security protocols that are based on zero-knowledge proofs. We show how several properties offered by zero-knowl...
