Risk Analysis on C-ITS Pseudonymity Aspects

Abstract

In the near future, vehicles will communicate with their environment by broadcasting Vehicle to everything (V2x) messages over the vehicular network (IEEE 802.11p). The exchanged messages contain data related to driver's privacy. As the laws in Europe require the privacy protection, the solution is to use pseudonym identities (certificates) in the communication. However, the use of these certificates can create new vulnerabilities that must be taken into account. In this paper, we do a state of art on the existing vulnerabilities, we applied the TVRA method and propose new vulnerabilities. Finally, we propose new countermeasures that could be implemented.
