CLA-FC5G: A Certificateless Authentication Scheme Using Fog Computing for 5G-Assisted Vehicular Networks

The functional characteristics of existing inter-vehicle communication networks are used to offer a certificateless authentication scheme that integrates fifth-generation (5G) communication and fog computing. Thus, CLA-FC5G, a novel certificateless authentication scheme for 5G-assisted vehicular networks equipped with fog computing and device-to-device communication in this paper. As opposed to prior schemes, which relayed on 802.11p-based inter-vehicle communication, our CLA-FC5G employs D2D technology, enabling vehicles to communicate directly while ensuring their respective safety and lightening the communication overhead. Our scheme contains six polynomial-time algorithms to handle the system setup, key generation, and message signing and verification processes. The results demonstrate that our method is both secure and efficient due to its lack of communication and computational overhead. We have discovered that our proposed CLA-FC5G system can lower overhead and is extremely efficient and scalable, which is well-suited for mass vehicular networks. The output reveals that CLA-FC5G, which affects both security and effectiveness, meets practical safety requirements for a believable 5G setting.
