In recent decades, as a green industry, electric vehicles (EVs) has a broader development perspective. Vehicle-Smart Grid ecosystem (V2G) intelligently and efficiently configures the electric energy between the electric vehicle and the grid, which can not only improve the efficiency of resource allocation, but also bring economic benefits to every entity in the system. Although the smart grid technology has become increasingly mature, security and privacy issues should not be ignored. To achieve these, a series of privacy-preserving authentication schemes have been designed for the V2G system. However, there are still some security problems like the problem of user anonymity. In order to address these issues, this work proposes a lightweight privacy-preserving authentication scheme using physical unclonable function (PUF). The proposed scheme can resist various known attacks such as impersonation attack and replay attack. Compared with previous related schemes in V2G system, our scheme has obvious advantages in terms of computing and communication overhead.
