Secure Communication Scheme of VANET with Privacy Preserving

This paper proposes a secure communication and privacy preserving scheme of Vehicular ad-hoc network (VANET). VANET improves road safety and traffic conditions via the vehicle exchange the traffic information with other vehicles and some infrastructures immediately. Ensuring that exchange messages are secure, trustworthy and protect user privacy are important issues. The transmission message must be well protected to ensure the integrity, confidentiality, anonymity and unlink ability. The transmission message must also satisfy trace ability and non-repudiation to guarantee the trusted third party can reveal misbehaving users. This proposed scheme is an efficient self-generated pseudonym mechanism based on Identity-Based Encryption (IBE) to provide privacy preservation. It also provides integrity, confidentiality, anonymity, trace ability and non-repudiation for VANET communications.
