Paper Title
Enhanced 4G LTE Authentication And Handover Mechanism

with the rapid development of information and network technologies, mobile communications plays an important role in our life and getting more attention for research. The 3GPP group proposed LTE mobile system to satisfy people high speed demand. In order to improve secure communication, the LTE deploys a hierarchical key management. However, during the X2 handover mechanism, current scheme is short of backward security and vulnerable to be attacked. In order to against the malicious base station and prevent the malicious attacks during the LTE x2 handover procedure, we propose an enhanced security features by group key to solve the above problems. Keywords: Group key; Handover; Security; Privacy.
