An Overview of Security Ongoing Work in Cooperative ITS

International audienceCooperative Intelligent Transport Systems (C-ITS) open the way to a large set of new applications that improve road safety and traffic and energy efficiency. However, this exposes vehicles to new security threats. Therefore, securing communication is paramount for ITS deployment that is why several research works are now focusing on emerging threats and countermeasures. This paper overviews the current state of security standards, research projects and existing security evaluation frameworks. The paper gives a qualitative comparison of the different project solutions, details the current security mechanisms integrated in the simulation platforms and discusses the open research challenges
