Chebyshev Polynomial Based Emergency Conditions With Authentication Scheme for 5G-Assisted Vehicular Fog Computing

Supporting vehicular emergency applications requires fast access to infrastructure so vehicles can call for help. Because of their environment's poor wireless qualities, vehicle infrastructure communication paths lack security. Modern authentication systems used to close security vulnerabilities require a lot of computing and storage power from the vehicle's OBU. Thus, a novel 5G automobile network emergency situations based on Chebyshev polynomial using fog computing and authentication is proposed. This is the first study to use Chebyshev chaotic mapping algorithm that uses a chaotic map, rotation, and XOR to generate a one-way hash and eliminate modular multiplication index or scalar multiplication on the elliptic curve. The proposed scheme has five stages: installation system, initialization, enrollment, mutual authentication, and emergency request. Critical to emergency services, the suggested protocol works better in resource-limited settings like car systems. The formal security analysis reveals that the suggested approach guarantees message authenticity and integrity, non-repudiation, traceability, unlinkability, identity privacy, certificate independence, and emergency response. The evaluation showed that the proposed method cannot execute forgery, impersonation, or replay attacks. The proposed method has lower computational, communication, and storage overhead than earlier efforts.
