An Efficient and Secure Anonymous Authentication Scheme for V2G Networks

The vehicle-to-grid (V2G) network has a clear advantage in terms of economic benefits, and it has grabbed the interest of powergrid and electric vehicle (EV) consumers. Many V2G techniques, at present, for example, use bilinear pairing to execute the authentication scheme, which results in significant computational costs. Furthermore, in the existing V2G techniques, the system master key is issued independently by the third parties, it is vulnerable to leaking if the third party is compromised by an attacker. This paper presents an efficient and secure anonymous authentication scheme for V2G networks to overcome this issue we use a lightweight authentication system for electric vehicles and smart grids. In the proposed technique, the keys are generated by the trusted authority after the successful registration of EVs in the trusted authority and the dispatching center. The suggested scheme not only enhances the verification performance of V2G networks and also protects against inbuilt hackers.
