A Cryptographically Sound Dolev-Yao Style Security Proof of an Electronic Payment System
We present the first cryptographically sound Dolev-Yaostyle security proof of a comprehensive electronic payment system. The payment system is a slightly simplified variant of t...

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...

Modeling Computational Security in Long-Lived Systems
Abstract. For many cryptographic protocols, security relies on the assumption that adversarial entities have limited computational power. This type of security degrades progressive...

On the composition of authenticated byzantine agreement
A fundamental problem of distributed computing is that of simulating a secure broadcast channel, within the setting of a point-to-point network. This problem is known as Byzantine...

A Cryptographically Sound Dolev-Yao Style Security Proof of the Otway-Rees Protocol
We present the first cryptographically sound security proof of the well-known Otway-Rees protocol. More precisely, we show that the protocol is secure against arbitrary active att...
