A multi-layered security protocol that enables a vehicle to take part in inter-vehicle communication for safety information is presented. The security protocol allows encapsulating security-sensitive systems, such as the brake assist system and isolates these systems from others. An inter-vehicle communication protocol should use methods to increase unlinkability of distinct messages. The certification protocol utilizes revocable blinded signatures and shared secrets to provide an adjustable tradeoff between authenticity and privacy. A multi-layered security protocol allows a vehicle to receive certificates, which are used for transferring traffic safety messages. The protocol combines different types of signatures schemes and while the TPM is only able to generate RSA signatures, the Secure Revocable Anonymous Authenticated Inter-Vehicle Communication (SRAAC) protocol uses the Digital Signature Standard (DSS).
