A generic multicast-key determination protocol

This paper examines a generic deadlock-free protocol for the automated maintenance of a commonly-shared multicast-key within a group in communication with each other. The protocol's use under conditions of both centralized and distributed controls is described. Distributed schemes are inherently more robust and more readily available compared with the centralized scheme of establishing the common multicast-key. Three schemes of use of the protocol are proposed. Simulation results are provided.
