Security against malicious node in the vehicular cloud computing using a software-defined networking architecture

Abstract

Recently Vehicular Cloud Computing (VCC) has become a significant research area, due to its potential to ensure passenger comfort and improve road safety. It has emerged as a promising technology that leverages the cloud computing functionalities to exploit vehicles underutilized computational, storage and communications. However, it has recently shown that the VCC might be vulnerable to various kinds of attacks, due to the public nature of its network. Therefore, ensuring security and privacy in this paradigm is considered as one of its most important challenges. In this paper, we exploit software-defined network (SDN) technology to design a new security approach that protects vehicles from malicious nodes, using pseudonyms, key management and revocation list which provides authentication, confidentiality, integrity and Availability.
