We propose in this paper a new approach to channel key management in the architecture S -SSM, we designed to secure SSM communication. S -SSM defines two mechanisms for access control and content protection. The first one is carried out through subscriber authentication and access permission. The second is realized through the management of a unique key, called the channel key, k ch, shared among the sender and subscribers. The management k ch is based on a novel distributed encryption scheme that enables an entity to efficiently add and remove a subscriber without affecting other subscribers.
