Abstract:
In a Smart Grid, a Vehicle to Grid (V2G) network aims to provide mobile distributed capacity of battery storage, helping to minimize the dependency of non-renewable energy sources. In this network, the privacy and anonymity of users’ identity, confidentiality of the transmitted data and location of the Electric Vehicle (EV) must be guaranteed. This article proposes a lightweight authentication protocol devoted to the protection of EV identities, prevention against the tracking of the vehicle and confidentiality of transmitted data. In a performance comparison with other protocols, the results from computing and communications performance analyses are better. The lower consumption of resources allows contributing for reducing signalling congestion and saving bandwidth. The protocol protects from various known attacks and security analysis shows that the protocol achieves the security goals.
