On the Composition of Public-Coin Zero-Knowledge Protocols
Abstract. We show that only languages in BPP have public-coin, blackbox zero-knowledge protocols that are secure under an unbounded (polynomial) number of parallel repetitions. Thi...

Joint State Theorems for Public-Key Encryption and Digital Signature Functionalities with Local Computation
Composition theorems in simulation-based approaches allow to build complex protocols from sub-protocols in a modular way. However, as first pointed out and studied by Canetti and ...

Design and Implementation of a Secure Group Communication Protocol on a Fault Tolerant Ring
In this paper, we describe a secure group communication protocol for a fault-tolerant synchronous ring. Our protocol, named Secure Synchronous Ring Protocol (SSRP), integrates a se...

Multiparty Computation for Dishonest Majority: From Passive to Active Security at Low Cost
Multiparty computation protocols have been known for more than twenty years now, but due to their lack of efficiency their use is still limited in real-world applications: the goal...

Entity authentication schemes using braid word reduction
Abstract. Artin's braid groups currently provide a promising background for cryptographical applications, since the first cryptosystems using braids were introduced in [2, 3, ...
