PROJECT TITLE :

Authentication Scheme for Flexible Charging and Discharging of Mobile Vehicles in the V2G Networks

ABSTRACT:

Navigating security and privacy challenges is one amongst the crucial needs within the vehicle-to-grid (V2G) network. Since electrical vehicles (EVs) need to provide their private data to aggregators/servers when charging/discharging at different charging stations, privacy of the vehicle homeowners can be compromised if the data is misused, traced, or revealed. In an exceedingly wide V2G network, where vehicles will move outside of their home network to visiting networks, security and privacy become even a lot of challenging thanks to untrusted entities in the visiting networks. Though some privacy-preserving solutions were proposed within the literature to tackle this drawback, they are doing not shield against well-known security attacks and generate an enormous overhead. Thus, we propose a mutual authentication theme to preserve privacy of the EV's information from aggregators/servers in the home as well as distributed visiting V2G networks. Our theme, primarily based on a bilinear pairing technique with an accumulator performing batch verification, yields higher system efficiency, defeats varied security attacks, and maintains untraceability, forward privacy, and identity anonymity. A performance analysis shows that our theme, compared with the prevailing solutions, significantly generates lower communication and computation overheads in the home and centralized V2G networks, and comparable overheads within the distributed visiting V2G networks.
