Security and privacy of electric vehicles in the smart grid context

Abstract

The technology, security and privacy requirements of the electric vehicle (EV) in the smart grid (SG) context, especially when the EV acts as mobile power storage, have gained much attention from the research community and market recently. This role of the EV is motivated by the increase in capacity of the power storages in the EV. In this paper, first we present different situations that an EV can be in the SG context and their privacy issues. Then, we provide two authentication schemes, first one between the EV and a trusted SG server directly, and second one via a non-trusted third party entity with a robust privacy-preserving agenda. Our analysis shows that our mechanisms are secure and robust enough to make sure the privacy of the customers is fully preserved, and at the same time, are efficient since they consume very limited resources.
