Assume that there are players and an eavesdropper Eve of unlimited computational power and that several pairs of players have shared secret keys beforehand. In a key sharing graph, each vertex corresponds to a player, and each edge corresponds to a secret key shared by the two players corresponding to the ends of the edge. Given a key sharing graph, a player wishes to send a message to another player so that the eavesdropper Eve and any other player can get no information on the message. In this paper, we first give a necessary and sufficient condition on a key sharing graph for the existence of such a unicast protocol. We then extend the condition to the case where a multiple number of players other than the sender and receiver passively collude. We finally give a sufficient condition for the existence of a secure multicast protocol.

Satellite multicast service expands the application of wideband multimedia satellite. Scheduling plays an important role to guarantee Quality of Service (QoS) for wideband multimedia multicast services. In this paper, considering various properties of QoS requirements of latency, throughput and priority, a PWBA multicast scheduling algorithm is proposed to balance trade-off between throughput and latency in order to providing better multimedia services in satellite networks. Comparing with the WBA and PGMF multicast scheduling policies, the proposed PWBA has better performances in both latency and throughput.
