A Novel Identity-Based Privacy-Preserving Anonymous Authentication Scheme for Vehicle-to-Vehicle Communication

This paper proposes a novel bilinear pairing-free identity-based privacy-preserving anonymous authentication scheme for vehicle-to-vehicle (V2V) communication, called “NIBPA”. Today, vehicular ad hoc networks (VANETs) offer important solutions traffic safety and efficiency. However, VANETs are vulnerable to cyberattacks due their use of wireless communication. Therefore, schemes used solve security privacy issues in VANETs. The NIBPA satisfies the requirements is robust cyberattacks. It also elliptic curve cryptography (ECC)-based lightweight scheme. pairing operation map-to-point hash function have not been because high computational costs. Moreover, it provides batch message verification improve performance. compared existing terms cost communication cost. test random oracle model (ROM). As result performance analysis, gives better results schemes.
