Secure multicast represents the core component of many web and multimedia applications such as pay-TV, teleconferencing, real-time distribution of stock market price and etc. The ...
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 ...
In this paper we propose an efficient key agreement protocol suite for heterogeneous mobile ad-hoc groups, whose members use mobile devices with different performance limitations...
Group key agreement (GKA) allows a set of players to establish a shared secret and thus bootstrap secure group communication. GKA is very useful in many types of peer group scenar...
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...
