沿着信息技术的发展，传统电网正在向智能电网技术发展。通过使用智能电网，用户和公用事业提供商可以更有效地管理和发电。沿着这些优势，智能电网也面临着新的安全问题。在智能电网中，用户的公民身份信息应该被保存，并且应该追踪攻击用户。对于一些低容量的设备，使用外包计算来执行复杂的计算是必不可少的。作者通过公共云提供外包计算。安全性和可追溯性是智能电网的两个重要安全属性。它们是对立统一的。在安全需求的基础上，提出了智能电网中外包小规模数据线性聚合（BAT-LA）的匿名性和可追溯性的平衡。给出了系统的形式化定义、系统模型和安全模型。然后，利用椭圆曲线密码体制和代理重加密技术设计了一个具体的BAT-LA协议。通过安全性分析和性能分析，证明了所设计的BAT-LA协议是安全有效的。
Along with the development of information technology, the traditional electrical grid is moving to smart grid technology. By using the smart grid, the users and utility providers can more efficiently manage and generate power. Along with the advantages, the smart grid is also faced with new security concerns. In the smart grid, the user's citizen identity information should be preserved and the offensive user should be traced. For some low-capacity devices, it is indispensable to perform complicated computation by using outsourcing computation. The authors provide the outsourcing computation through public cloud. Anonymity and traceability are two important security properties in the smart grid. They are the unity of opposites. On the basis of the security requirements, they propose the balanced anonymity and traceability for outsourcing small-scale data linear aggregation (BAT-LA) in the smart grid. The formal definition, system model and security model are presented. Then, a concrete BAT-LA protocol is designed by using the elliptic curve cryptography and proxy re-encryption. Through security analysis and performance analysis, the designed BAT-LA protocol is provably secure and efficient.
