Computationally Efficient and Secure Session Key Agreement Techniques for Vehicular Cloud Computing

Vehicular cloud computing (VCC) has emerged as a new technology to present better and uninterrupted information to traffic management and road safety. However, the exchange of information among all different vehicles, device and roadside infrastructure over the public network presents a favorable scenario to the adversary to perform active and passive attacks. Therefore, there is an organizing demand for an efficient and secure architecture of the secure exchange of information in VCC. In this direction, one of the big challenges is to mutually authenticate the legitimate sources of the information provider and receiver, and then to manage secure session among them. To ensure secure and authorized communication in VCC, this paper discusses the construction of the authenticated session key agreement protocol for VCC. The proposed framework also maintains the anonymity of participating vehicles. The proposed protocol requires fewer computations from the user side as compare to the cloud server and roadside infrastructures. Moreover, the proposed scheme is theoretically proved secure in the random oracle model. Proposed scheme’s performance analysis and comparison with related results on security and performance attributes keep it ahead.
