In the duration of handover, coordinated multipoint (CoMP) joint transmission can help not only improve the throughput but also reduce the interference at cell edges. However, the current secure handover key management scheme in LTE-A system has not yet supported the CoMP joint transmission handover. Therefore, to solve the problem, in this paper, we present a novel secure CoMP joint transmission handover key management scheme in LTE-A vehicular networks. Specifically, to achieve the diversity gain brought by the CoMP joint transmission and accommodate to protect the backward/forward key separation, the session key is generated by the vehicle and securely delivered towards the cooperating eNBs, and then decrypted by each cooperating eNB respectively. Security analysis shows that the proposed scheme can successfully establish session keys with the cooperating eNBs during the CoMP joint transmission handover with backward/forward key separation. In addition, performance evaluation is conducted to demonstrate the feasibility of the proposed scheme.
