Multi Group Key Agreement Mechanism for Mobile P2P Wireless Networks

چکیده
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.

In the infrastructure-less disaster environment, the application of the peer-to-peer (P2P) group conference over mobile ad hoc network (MANET) can be used to communicate with each other when the rescue crews search the survivors but work separately. However, there still are several problems of in-time multimedia delivery in P2P-MANET: (1) MANET mobility influences the maintenance of P2P overlay...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...
