A Cost-Effective Identity-Based Signature Scheme for Vehicular Ad Hoc Network Using Hyperelliptic Curve Cryptography

A Vehicular Ad Hoc Network (VANET) is a subset of the Mobile (MANET) that allows vehicles to communicate with each other and roadside stations offer efficient safe transportation. Furthermore, when VANET used in connection Internet Things (IoT) devices sensors, it can help traffic management road safety by allowing interact one another at any time from location. Since VANET’s event-driven communications are carried out via an open wireless channel, there significant security concerns. In this paper, we use Hyperelliptic Curve Cryptography (HECC) cost-effective identity-based signature for secure communication over VANET. The proposed scheme does not need certificate management, found more against variety cryptographic threats after conducting thorough analysis. addition, comparisons computational costs made, demonstrating both respects than existing schemes.
