基于量子密钥分发的新型城镇电力业务安全交互架构

Security Interaction Framework for Electricity Service in New-type Town Based on Quantum Key Distribution

电力系统规模庞大、微电网众多、网络边界模糊且运行环境复杂多样,使得传统城镇电网的安全威胁日益尖锐。为适应新型城镇化的发展需求,弥补电力设备加密密钥在线更新及时性不足的问题,对电力量子保密通信实用化技术和核心业务特征进行研究,提出了新一代高安全等级保护的电力量子保密通信架构,用以提升电力信息加密传输的安全级别。基于实际城镇电网线路和试验环境开展所提方案的性能测试,结果表明所提方法满足电力业务的运营需求,可有效提升电网的安全防护能力。

The large power system,numerous microgrids,blurred network boundaries,and complex,diverse operation environments make the security threats of traditional urban power grids increasingly serious.In order to meet the development requirements of new-type urbanization and make up for insufficient timeliness of online updating of power equipment encryption keys,this paper studies the practical technology and core service characteristics of power quantum secret communication.A new generation of power quantum secure communication framework with high-security level protection is proposed to improve security level of electricity information transmission.The performance test of the proposed scheme is conducted based on the actual urban power transmission line and test environment.The results show that the proposed method can meet the operation requirements of the electricity business.Moreover,it can effectively improve the security protection capability of power grid.
