智能电网中家域网安全数据汇聚与调度方法研究

智能电网中通信网络的安全是实施智能电网的一个重要环节。用户信息的隐私保护是智能电网安全服务的一个主要任务。智能电网中用户信息隐私保护主要围绕智能电表数据的机密性和匿名性展开。本文以家域网作为智能电网通信网络的一个基本数据汇聚与调度单元,提出了一种安全的网内数据汇聚与调度方法,从而保证了智能家居设备的用电信息的机密性和匿名性。采用NS-2对本文提出的网内方法进行了仿真研究。仿真结果表明,本文提出的网内数据汇聚与调度方法与传统方法相比具有较高的实用性。

A Secure Data Aggregation and Dispatch Scheme for Home Area Networks in Smart Grid

Cyber security for smart grid communication systems is one of the most critical requirements need to be assured before smart grid can be operationally ready for the market. The customer information privacy in smart grid needs to be protected. Smart grid data privacy encompasses confidentiality and anonymity of the information extracted from smart metering in a smart grid communication system. In this paper,we consider a home area network as a basic data aggregation and dispatch unit in smart grid systems,and propose a secure in-network data aggregation and dispatch scheme to keep the confidentiality and anonymity for power usage information of smart home devices. Simulation studies are conducted to test the performance on different metering datasets for the proposed scheme. Simulation results indicate that compared with the traditional schemes,the proposed scheme has better performances in confidentiality and anonymity.
