摘　　要：由于现有V2G认证方案中未考虑车辆移动特性,导致跨域车辆与不同地区电网服务器进行通信和交互时,无法有效完成跨域认证过程。此外,车辆到达目的域进行跨域认证时需要与注册域服务器进行频繁通信导致跨域认证效率低下。针对以上问题,提出一种基于切比雪夫混沌映射的V2G跨域双向认证方案。所提方案中,首先快速认证聚合器的物理安全并协商出聚合器与电网服务器的临时会话密钥完成一层认证,保证了区块链中节点查询链上信息的传输保密性;利用智能卡存储的认证参数完成聚合器与跨域车辆之间的二层认证,优化了车辆与注册域聚合器的繁琐通信过程,进一步降低了通信开销。理论分析和实验结果表明,所提方案可以实现安全高效的跨域认证。Due to the fact that existing V2G(Vehicle-to-Grid)authentication schemes fail to consider the mobility characteristics of vehicles,they are unable to effectively complete the cross-domain authentication process when cross-domain vehicles communicate and interact with grid servers in different regions.Additionally,when vehicles arrive at their destination domain for cross-domain authentication,they need to communicate frequently with the server in their registered domain,resulting in inefficient cross-domain authentication.To address these issues,a V2G cross-domain mutual authentication scheme based on Chebyshev chaotic map is proposed.In the proposed scheme,firstly,the physical security of the aggregator is quickly verified,and a temporary session key between the aggregator and the grid server is negotiated to complete the first layer of authentication,ensuring the confidentiality of information transmission during node queries on the blockchain.The second layer of authentication between the aggregator and the cross-domain vehicle is completed using authentication parameters stored on a smart card,which optimizes the cumbersome communication process between the vehicle and the aggregator in the registered domain and further reduces communication overhead.Theoretical analysis and experimental results demonstrate that the proposed scheme can achieve secure and efficient cross-domain authentication.
