Securing group communications in resource constrained, infrastructure-less environments such as Mobile Ad Hoc Networks (MANETs) has become one of the most challenging research dire...
Cryptographic protocols can be divided into (1) protocols where the protocol steps are simple from a computational point of view and can thus be modeled by simple means, for insta...
We study the design of cryptographic primitives resilient to key-leakage attacks, where an attacker can repeatedly and adaptively learn information about the secret key, subject o...
The majority of current security architectures for grid systems use public key infrastructure (PKI) to authenticate identities of grid members and to secure resource allocation to...
In this paper we describe the advantages of using iterative Diffie-Hellman (IDH) key trees for mobile ad-hoc group communication. We focus on the Treebased Group Diffie-Hellman (...
