In a Vehicular Cloud (VC), underutilized vehicular resources including computing power, data storage, and internet connectivity can be shared between rented out over the Internet to various customers. If the VC concept is to see a wide adoption and to have significant societal impact, security and privacy issues need to be addressed. The main contribution is to detect and examine a number of security challenges and potential privacy threats in VCs. Even though security issues has received the attention in cloud computing and vehicular networks, the authors identified security challenges that are special to VCs, e.g., challenges of authentication of high-mobility vehicles, scalability and the complexity of establishing trust relationships among multiple players caused by intermittent short-range communications.
