xxTEA-VCLOUD: A Security Scheme for the Vehicular Cloud Network using a Lightweight Encryption Algorithm

The recent developments in the field of cloud computing and the increasing number of vehicles on roads have led to develop a method that exploits underutilized vehicular resources called the vehicular cloud computing (VCC). It is a paradigm that combines the vehicular ad hoc network VANET and the cloud computing to benefit from their advantages and to provide road safety to drivers. However, authentication and confidentiality are considered as the most challenging issues in VCC. To cope with those challenges, we propose a new security mechanism for the vehicular cloud based on the implementation of a lightweight encryption algorithm with several techniques to ensure authentication and confidentiality.
