Efficient authentication is one of important security requirements in mobile ad hoc network (MANET) routing systems. The techniques of digital signatures are generally considered a...
We study the security of the widely deployed Secure Session Layer/Transport Layer Security (TLS) key agreement protocol. Our analysis identifies, justifies, and exploits the modul...
Abstract. We examine the popular proof models for group key establishment of Bresson et al. [BCPQ01,BCP01] and point out missing security properties addressing malicious protocol p...

Group signature schemes are cryptographic systems that provide revocable anonymity for signers. We propose a group signature scheme with constant-size public key and signature leng...
We introduce Ad Hoc Anonymous Identification schemes, a new multi-user cryptographic primitive that allows participants from a user population to form ad hoc groups, and then prove...
