Modular Security Proofs for Key Agreement Protocols
The security of key agreement protocols has traditionally been notoriously hard to establish. In this paper we present a modular approach to the construction of proofs of security ...

Tripartite Key Exchange in the Canetti-Krawczyk Proof Model
A definition of secure multi-party key exchange in the Canetti-Krawczyk proof model is proposed, followed by a proof of the security of the Joux tripartite key agreement protocol...

Provably Secure Grouping-Proofs for RFID Tags
We investigate an application of RFIDs referred to in the literature as group scanning, in which several tags are "simultaneously" scanned by a reader device. Our goal is...

Real-or-random Key Secrecy of the Otway-Rees Protocol via a Symbolic Security Proof
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...

Limits of Constructive Security Proofs
The collision-resistance of hash functions is an important foundation of many cryptographic protocols. Formally, collision-resistance can only be expected if the hash function in f...
