In this paper we describe an efficient algorithm for the management of group keys. Our algorithm is based on a protocol for secure IP-multicast and is used to manage group-keys in group-communications systems. Unlike prior work, based on centralized key-servers, our solution is completely distributed and fault-tolerant, and its performance is comparable to the centralized solution.
