A Novel Key Distribution Scheme for Efficient Group Communication in MANET

Mobile ad-hoc Network (MANET) is collection of mobile platforms that form a dynamic infrastructure communication network wherever required. Until recently, Mobile nodes formed a group communication, even for communication there is a problem of efficient and securely broadcast from sender to remote cooperative group occurs in many emerging applications. In Existing consider several distributed collaborative group key management had unavailability of a fully trusted key generation procedure. To overcome the problem, this paper proposed a new key management to ensure the safety of group key and to protect the group communication. In propose a tesla based triple key encryption to protect communication group by using a novel key approach, its implementation affability without relying on a fully trusted authority provide our protocol a very promising solution to many applications. Furthermore, our scheme provides basic strategies of member addition/deletion and rekeying operation for cooperative group.
