In this paper we describe an efficient algorithm for the management of group-keys for Group Communication Systems. Our algorithm is based on the notion of key-graphs, previously u...
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 ...
A prerequisite for secure communication between two nodes in an ad hoc network is that the nodes share a key to bootstrap their trust relationship. In this paper, we present a sca...
Abstract— In this paper, we propose a non-commutative keyexchange scheme which generalizes the classical ElGamal Cipher to polycyclic groups. We will explore other classes of gro...
As multicast applications are deployed for mainstream use, the need to secure multicast communications will become critical. Multicast, however, does not t the point-to-point mod...
