Multi Group Key Agreement Mechanism for Mobile P2P Wireless Networks

Secure and efficient communication among a set of mobile nodes is one of the most important aspect in P2P wireless networks. Security of various group-oriented applications requires a group secret shared between all participants. Several group key protocols have been presented in the literature to enable secrecy of communication among dynamic group of participants. However, most of them suffer from the scalability problem. In this paper, we propose a novel multi group key agreement mechanism for P2P wireless network. The proposed model is organized as several neighboring rings. Each group of peer belonging to the same ring has to agree on a contributed key, and the peer belonging to two adjacency rings have one key for each ring. Then, only a small set of nodes has to recalculate the key in case of join or leave operations.
