In this paper, we propose a novel secure and privacy-preserving solution for V2X systems leveraging widely accepted trusted computing technologies. Our approach systematically addresses all key aspects, i.e., security, privacy and accountability (revocation). By reflecting on state-of-the-art pseudonym architectures, we identify their limitations focusing on pseudonym reusage policies and revocation mechanisms. We propose the use of Direct Anonymous Attestation (DAA) algorithms to enhance existing V2X security architectures. The novelty of our proposed solution is its decentralized approach in shifting trust from the infrastructure to vehicles. Applying DAA in V2X enables enhanced privacy protection than is possible in current architectures through user-controlled linkability. The paper presents the incorporation of DAA algorithms within V2X together with rigorous security and privacy arguments.
