智能电网下隐私保护技术研究与应用

摘要

随着智能电网的飞速发展,基于移动通信技术的电网系统移动业务应用也越来越广泛,如智能电表,电动汽车(插电式汽车),线路巡检、设备巡检等,但是智能电网中各类不同的使用者通信暴露出了许多安全和隐私问题.论文主要研究了电动汽车在智能电网中的隐私保护问题.并设计了一种电动汽车到智能电网中具有隐私保护性能的安全通信模型,在该模型中提出了一种基于计算性复杂理论的同态加密的隐私保护方案.最后通过实验仿真结果证明该算法在汽车到电网接入技术中更容易避免消息分析攻击和消息修改攻击,因此不易泄露信息.%With the rapid development of smart grid,grid system based on mobile business application of mobile communica?tion technology is more and more widely used,such as smart meters,electric vehicles(plug-in vehicles),line inspection,equip?ment inspection and so on,But in the smart grid,all kinds of users in the smart grid are exposed to a lot of security and privacy is?sues. This paper mainly studies the privacy protection of electric vehicle in smart grid. A secure communication model with privacy protection performance in the smart grid is designed,and a privacy protection scheme based on the complex theory of computational complexity is proposed. Finally,the simulation results show that the proposed algorithm is more easy to avoid the attack of message analysis and message modification,so it is not easy to leak information.
