The 4G Long Term Evolution (LTE) is used to provide continuous communication for the mobility based users with high data rate in 4G network. However, the security issues are of paramount importance and have been a recent research area in LTE. The desynchronization attack is one of the major security threats in LTE during handover key management that occurs when source node acts as a rogue base station in order to hijack the future session key. The paper addresses the vulnerability of desynchronization attack in 4G LTE and elucidates how the attack jeopardizes the communication. Also, the paper proposes a secured and efficient handover scheme in key management using identity based encryption to authenticate the participating principals in LTE before the node tries to communicate with the target base station. The scheme is validated using a model checker - AVISPA. The analysis of security and performance evaluation shows that the proposed scheme provides an enhanced security and significant reduction in the communication cost for authentication and key generation in LTE. © International Science Press.
