摘要

Although vehicles in fifth-generation (5G)-enabled vehicular fog computing can share data (such as traffic status) with others to improve traffic efficiency and driver safety, privacy and security are still significant obstacles that must be overcome. As a result, several experts in the field have offered different methods to ensure safe vehicle-to-vehicle communication. However, these methods often are not yet ready for rollout in automotive networks. However, there are still restrictions, such as the need for a roadside unit (RSU), the difficulty of using on-board storage, and the susceptibility to side-channel attacks. This work is motivated by the need to present an innovative method for 5G-enabled vehicular fog computing, one that eliminates the aforementioned problems through the use of blockchain technology to ensure the security of data exchanged between vehicles. In order to ensure safe communication between vehicles, we propose using PKI derived from a public blockchain (Ethereum). Also, our proposed solution employs a key generation mechanism to ensure effective certificate management is implemented. The concept not only passes muster with regulators, but it can also withstand intrusion attempts. We test our solution on the Rinkeby test network and provide a pair of simulators (NS-2 and Vanet-MobiSim) to measure the rate of authentication information loss and its latency.
