Scalable multicast security with dynamic recipient groups

Molva, Refik;Pannetrat, Alain

ACM Transactions on Information and System Security, Voume 3, N°3, August 2000

In this paper we propose a new framework for multicast security based on distributed computation of security transforms by intermediate nodes. The involvement ofintermediate nodes in the security process causes a new type of dependency between group membership and the topology of the multicast network. Thanks to this dependency, the containment ofsecurity exposures in large multicast groups is assured. The framework also assures both the scalability for large dynamic groups and the security of individual members. Two different key distribution protocols complying with the framework are introduced. The first protocol is an extension of the ElGamal encryption scheme whereas the second is based on a multi-exponent version of RSA.
