摘　　要：为实现智能电网数据的安全汇总和访问控制的有效结合,在同态加密的基础上,结合陷门秘密分享技术,提出一种基于多方认证的智能电网访问控制方案。通过对智能电表中数据密文进行同态加密处理,保证数据从智能电表到变电站传输过程的安全,同时对汇总的密文数据进行属性化,可实现对数据访问者的多方认证访问控制。实验数据结果表明,该方案具有可行性和实用性。In order to realize the effective combination of security aggregation and access control of smart grid data,based on homomorphic encryption,combined with trapdoor secret sharing technology,a smart grid access control scheme based on multi-party authentication is proposed.Homomorphic encryption is performed on the cipher text of the data in the smart meter to ensure the security of data transmission from the smart meter to the substation.At the same time,the summarized ciphertext data is attributed to achieve multi-party authentication access control for data visitors.The experimental data results indicate that the scheme is feasible and practical.
