An overview of security aspects and solutions in VANETs

Because of the nature of vehicular communications, security is a crucial aspect, involving the continuous development and analysis of the existing security architectures and punctual theoretical and practical aspects that have been proposed and are in need of continuous updates and integrations with newer technologies. But before an update, a good knowledge of the current aspects is mandatory. Identifying weaknesses and anticipating possible risks of vehicular communication networks through a failure modes and effects analysis (FMEA) represent an important aspect of the security analysis process and a valuable step in finding efficient security solutions for all kind of problems that might occur in these systems.
