Abstract:

Considering the problem of identity privacy leakage during charging and discharging between vehicles and grids, this paper proposes a cross-domain identity authentication scheme for vehicles in V2G. In this paper, elliptic curve encryption(ECC) algorithm and elliptic curve digital signature algorithm(ECDSA) are used to ensure the privacy of data and the authenticity of identities among grid servers, and use the blockchain to host the server public key certificate. For the authentication between the charging pile and the grid server, the faster symmetric encryption algorithm(AES) and message authentication code(MAC) are used to ensure the privacy and authenticity of the data. The scheme also uses the physical unclonable technology PUF lightweight and anti-physical attack characteristics to achieve the practicability and effectiveness of the scheme. Finally, compared with other schemes and experimental simulations, this scheme has better security, integrity, light weight and efficiency.
