摘　　要：智能电网作为新一代的电力系统,显著提高了电力服务的效率、可靠性和可持续性,但用户侧信息安全问题也日渐突出.本文针对智能电网系统中用户数据信息泄露的问题,提出了一个具有隐私保护的数据安全采集方案.收集器能够对采集到的电表数据进行验证,聚合为一个新的数据包,发送给电力服务中心解密和存储,且第三方仲裁机构能够解决用户端智能电表与电力服务中心发生的纠纷.同时,本方案支持收集器,电力服务中心和第三方仲裁机构执行批量验证操作,以提升验证效率.本文的理论分析与实验比较表明,该方案比同类型方案具有更高的运算效率和通信效率.Smart gird is a new generation of power system,which significantly improves the efficiency,reliability and sustainability of power service.However,the issue of privacy information leakage of users in smart grid is becoming increas-ingly prominent.To address this problem,we propose a privacy-preserving data security collection scheme,where the collec-tor is able to verify all the collected data and aggregate them into a new data packet,then send it to the electricity service provider(ESP)for decryption and storage.This paper also introduces a third-party to arbitrate disputes between the smart meter users and ESP.In our solution,collectors,ESP,and the third-party can perform batch verification on multiple(aggre-gated)ciphertexts,respectively,so as to efficiently verify their authenticity and integrity.The theoretical analysis and experi-mental comparison show that the proposed scheme enjoys more computational efficiency and communication efficiency com-pared with existing scheme.
