Incorporating electric vehicles into smart grid, vehicle-to-Grid (V2G) makes it feasible to charge for large-scale electric vehicles, and in turn support electric vehicles, as mobile and distributed storage units, to discharge to smart grid. In order to provide reliable and efficient services, the operator of V2G networks needs to monitor realtime status of every plug-in electric vehicle (PEV) and then evaluate current electricity storage capability. Anonymity, aggregation and dynamic management are three basic but crucial characteristics of which the services of V2G networks should be. However, few of existing authentication schemes for V2G networks could satisfy them simultaneously. In this paper, we propose a secure and efficient authentication scheme with privacy-preserving for V2G networks. The scheme makes the charging/discharging station authenticate PEVs anonymously and manage them dynamically. Moreover, the monitoring data collected by the charging/discharging station could be sent to a local aggregator (LAG) in batch mode. In particular, time overheads during verification stage are independent with the number of involved PEVs, and there is no need to update the membership certificate and key pair before PEV logs out.

Existing System	Proposed System
Ø  In existing system, power grid isonly used. In power cut time inverters are used and once the charge in the inverter get over then we cannot able to use       Drawbacks of existing system: Ø  Power shortage exists Ø  Power cuts are more Ø  Rechargeable inverters	Ø  In proposed system, both renewable and non renewable energy sources are used.         Advantage of proposed system:       Using non renewable energy source       Highly reliable Ø  More flexible
