FC-PA: Fog Computing-Based Pseudonym Authentication Scheme in 5G-Enabled Vehicular Networks

The fifth-generation (5G) technology-enabled vehicular network has been widely used in intelligent transportation recent years. Since messages shared among vehicles are always broadcasted by openness environment’ nature, which is vulnerable to several privacy and security problems. To cope with this issue, researchers have proposed pseudonym authentication schemes for the 5G-enabled network. Nevertheless, these applied complected time-consumed operations. Therefore, paper proposes a fog computing-based (FC-PA) scheme decrease overhead of performance networks. FC-PA applies only one scalar multiplication operation elliptic curve cryptography prove information. A analysis our work explains that satisfies privacy-preserving authentication, resilient against common attacks. With efficiency, can obtain better trade-offs between efficiency than well-known works.
