【摘要】：智能电网作为替代传统电网的新一代电网，集成了先进的通信与信息技术，实现了供应商与用户之间电能的优化传输与配送。然而，智能电网中通信网络带来的隐私保护与信息安全问题亟待解决。结合智能电网采集数据场景以及通信网与设备的特点，基于假名、同态加密和基于身份聚合技术，论文提出了一个智能电网中的聚合安全方案，解决了远程终端向电网控制中心发送海量数据的隐私保护与安全通信问题，并对方案进行了安全性与性能分析。结合智能电网中广播数据场景，，使用基于属性加密和基于身份签名技术，论文提出了一个智能电网中的定向广播安全方案，解决了电网控制中心向远程终端定向广播控制数据的问题，并对方案进行了安全性与性能分析。论文分别提出的智能电网中聚合与定向广播安全方案，可以看作一个完整的双向安全通信方案。
[Abstract]:As a new generation of power grid replacing traditional power grid, smart grid has integrated advanced communication and information technology to achieve optimal transmission and distribution of power between suppliers and users. However, the problem of privacy protection and information security caused by the communication network in the smart grid needs to be solved urgently.
Based on the characteristics of collecting data scene in smart grid and the characteristics of communication network and equipment, based on pseudonym, homomorphic encryption and identity based aggregation technology, this paper proposes a polymerization security scheme in the smart grid, which solves the hidden protection and security communication problems of the remote terminals sending massive data to the power grid control center, and the scheme is carried out. Safety and performance analysis.
Combining the broadcast data scene in the smart grid and using the attribute encryption and identity based signature technology, a directional broadcast security scheme in the smart grid is proposed, which solves the problem of the directional broadcast control data from the power grid control center to the remote terminal, and the security and performance analysis is carried out in the other case.
The proposed scheme of aggregation and directional broadcast in smart grid can be regarded as a complete two-way secure communication scheme.
