摘要
文章结合智能电网的特征和发展趋势,分析了目前智能电表中用户隐私保护主要包括的电表实时发送数据阶段和记账阶段两部分,通过加密和认证等技术对智能电网中用户的隐私信息进行保护。然而,现有的智能电网隐私保护认证技术大多不够完善,通过公钥加密系统保护智能电网的安全愈发重要,而基于全同态加密的安全和高效的智能电网数据交换是当前信息安全研究热点问题之一。因此,文章针对数据交换方案,提出一个基于全同态加密技术的加密系统。文章所构造的智能电网隐私保护方案具有强安全性和高效的用户隐私保护特性,保证了用户隐私数据的机密性和完整性。
This paper combines with characteristics and development trend of smart grid,analyzes user privacy smart metering including meter real time data phase and billing stages in two parts,and protects users＇ privacy information in the smart grid by means of encryption and authentication technology.However,most of existing smart grid privacy protection technology is not perfect; by a public key encryption system to protect the security of the smart grid is more important.Homomorphic encryption security and efficient smart grid data exchange is one of the hot issues of current information security research.Therefore,for data exchange,this paper proposes an encryption system based on homomorphic encryption technology.The smart grid privacy protection scheme has strong security and efficient privacy protection features,ensuring user privacy,confidentiality and integrity of data.
