An Efficient Secure group key management system in wireless ad hoc network

The problem of efficiently and securely broadcasting to remote cooperative group occurs in many newly emerging networks. A major challenge in devising such systems is to overcome the obstacles of the potentially limited communication from the group to the sender, the unavailability of a fully trusted key generation center, and the dynamics of the sender. The existing key management paradigms cannot deal with these challenges effectively. This paper proposes and specifies a protocol for distributing and managing secure group keys in ad hoc environments, which applies for the Secure Optimized Link State Routing Protocol (SOLSR). Our protocol manages group keys taking into consideration the frequent network partitions and the absence of infrastructure. The analysis shows that the protocol is energy efficient for high key replacement rates and frequent network partitions. We have using an Energy Efficient Group key management (EEGK) for secure data processing on network. A provably secure protocol in the new key management paradigm and perform extensive experiments in the context of mobile ad hoc networks. In the proposed protocol after extraction of the public group encryption key in the first run, the subsequent encryption by the sender and the decryption by each receiver are both of constant complexity, even in the case of member changes or system updates for rekeying.
