A Lightweight Cross-domain Mutual Authentication Scheme in V2G Networks

针对车辆与电网充放电时身份隐私泄露问题,文章提出一种轻量级的跨域身份认证方案。方案采用ECC和ECDSA保证电网服务器之间数据的隐私性和身份的真实性,同时利用区块链托管服务器公钥证书。对于充电桩到电网服务器之间的认证,采用速度更快的对称加密算法AES和消息认证码MAC保证数据的隐私性和真实性。文章利用PUF技术的轻量级和抗物理攻击特性提高了方案的实用性和有效性。通过与其他方案对比和实验仿真表明,该方案具有更好的安全性、完整性、轻量级和高效性。

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.
