Vehicular Cloud Computing Security: A Survey

Vehicular ad hoc networks (VANETs) have recently gained a lot of interest. This is due to their capacity to improve driving safety and traffic management. VANET is designed to provide emerging applications and services to drivers in vehicular environments. On the one hand, the rapid advancement of automobile industry enables the development of vehicles with various forms of onboard computation facilities, storage, communication and sensing resources. On the other hand, the application of cloud computing (CC) affects several domains, including the transportation domain, therefore the emergence of vehicular cloud computing (VCC). VCC is an efficient technology to move VANET toward autonomous driving, vehicle control, and intelligent systems. Security and privacy issues are among the major concerns that should be addressed in the context of VCC. However, the special characteristics of VCC have made the security used in classical VANET and CC to be revised. To the best of our knowledge, there is a lack of security surveys for VCC. This paper is an attempt to discuss the challenges faced by security for VCC and future guide to handling these challenges.
