Intelligent transportation systems are on their way toward wide deployment. Vehicle to everything (V2X) communication, as an enabler for safer and more convenient transportation, has attracted growing attention from industry and academia. However, security and privacy concerns of such communication must be addressed before it can be widely adopted. In this paper we analyze the security and privacy requirements of V2X communication. Specifically, we focus on lawful identity resolution (i.e., de-anonymization) in V2X communication, and consider recent regulatory changes in this area. Based on this, we define an expanded set of technical requirements for identity resolution in V2X communication. We then propose a solution for the problem statement where the involved parties may be dishonest but not colluding.
