Adaptive Security of Concurrent Non-Malleable Zero-Knowledge
A zero-knowledge protocol allows a prover to convince a verifier of the correctness of a statement without disclosing any other information to the verifier. It is a basic tool a...

A Causal Analysis Method for Concurrent Hybrid Automata
Modern artifacts are typically composed of many system components and exhibit a complex pattern of continuous/discrete behaviors. A concurrent hybrid automaton is a powerful model...

On the Concurrent Composition of Zero-Knowledge Proofs
We examine the concurrent composition of zero-knowledge proofs. By concurrent composition, we indicate a single prover that is involved in multiple, simultaneous zero-knowledge pro...

Concurrent Kleene Algebra
Abstract. A concurrent Kleene algebra offers, next to choice and iteration, operators for sequential and concurrent composition, related by an inequational form of the exchange la...

Information-theoretically secure protocols and security under composition
We investigate the question of whether security of protocols in the information-theoretic setting (where the adversary is computationally unbounded) implies the security of these ...

Simulatable Security and Polynomially Bounded Concurrent Composability
Simulatable security is a security notion for multi-party protocols that implies strong composability features. The main definitional flavours of simulatable security are standa...

On the Necessity of Rewinding in Secure Multiparty Computation
We investigate whether security of multiparty computation in the information-theoretic setting implies their security under concurrent composition. We show that security in the sta...
