We present a provably secure tree based authenticated group key agreement protocol in dynamic scenario. Bilinear pairing and multi-signature are at the heart of our protocol. We p...
Secure and reliable group communication is an increasingly active research area by growing popularity in group-oriented and collaborative application. One of the important challeng...

Design of protocols for mobile ad-hoc networks (MANETs) is generally tricky compared to wired networks, because on the one hand the increased communication constraints given by th...
This paper considers the problem of key agreement in a group setting with highly-dynamic group member population. A protocol suite, called CLIQUES, is developed by extending the w...
We present an efficient authenticated and fault-tolerant protocol (AFTD) for tree-based key agreement. Our approach is driven by the insight that when a Diffie-Hellman blinded key ...
