Mind Your Right to Know: On De-anonymization Auditability in V2X Communications

Intelligent transportation systems are getting close to wide deployments. Vehicle to everything (V2X) communication as 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 reaching to a wide adoption. In this paper we analyze the security and privacy requirements of V2X communications and more specifically, elaborate on a new requirement regarding identity resolution in V2X communication which is absent in majority of previous work in this context. We believe that in near future similar requirements would be introduced by rulemaking authorities. Moreover, we refer to a recent case to back up our justification. We then propose a basic solution for the problem statement where just only one of the involved parties is dishonest.
