基于TCM的智能电表隐私保护协议

A protocol of privacy protection for smart meters based on TCM

通过对智能电表向智能控制中心报告的实时电量消费数据的分析,可以得到用户的生活习惯和经济状况等隐私信息.在个人隐私日益受到关注的今天,用户隐私信息保护成为制约智能电网快速发展的重要因素之一.本文基于我国自主知识产权的可信密码模块,提出了具有隐私保护功能的智能电表实时用电量传输协议.使用环签名方案隐藏了用户身份,使用平台属性证书隐藏了智能电表平台配置,并在随机预言模型下证明协议的安全性.本协议研究不仅对智能电网隐私保护具有重要的理论意义,而且使可信计算技术具有一定的应用价值.

Through the analysis of the real-time electricity consuming data from the smart meters sent to the intelligent control center, the user＇s private information such as personal habits and e- conomic state etc could be obtained. Nowadays, the personal privacy has received more and more attentions. The privacy protection is one of the most important factors to restrict the development of the smart grid. A smart meter real-time electricity transmission protocol is proposed based on the trusted cryptography module（TCM） with intellectual property rights. In this protocol, the ring signature is used to hide the user＇s identity and the platform attribute certificates are applied to hide the platform configurations of smart meters. The security of the protocol has been proved in the random predication model. This study has the significant references for the smart grid pri- vacy protection and also has good applications in trusted computing.
