Secure and Efficient Distributed Relay-Based Rekeying Algorithm for Group Communication in Mobile Multihop Relay Network

In mobile multihop relay (MMR) networks, Relay multicast rekeying algorithm (RMRA) is meant to ensure secure communication and selective updating of keys in MMR networks. However, RMRA, the carried out after a specific interval time, which cannot security for on joining member. Secondly, scheme generates huge overhead serving base station (MR-BS) frequent members. Lastly, there nothing about when member left group communication. Thus, RMRA fails provide forward backward secrecy also not scalable. To solve this problem, an improved based broadcasting new seed value leaving ongoing key management proposed. The proposed solves issue scalability very simplified way. has been extensively validated by formal method using rank theorem. Furthermore, mathematical derivation showed that out-performed terms cost complexity.
