基于MDI-QKD协议的国际业务数据传输方案研究

摘要/Abstract

摘要： 电力信息系统数据的安全传输，尤其是国际业务数据的安全传输关系着整个电网的安全运行。无条件安全的量子通信技术可大幅提高系统数据传输的安全级别，并提供对窃听者的可检测性。通过对与测量设备无关量子密钥分发(MDI-QKD)的原理分析，针对电力业务的特殊性，提出将MDI-QKD协议应用到传统的电力系统国际业务数据传输的“即插即用”MDI-QKD方案，方案包括测量控制中心、外网国际业务专区和海外传输前置区三部分，测量控制中心负责光脉冲的产生和贝尔态的测量，外网国际业务专区和海外传输前置区通过密钥管理端口与量子虚拟专用网（VPN）相连，实施数据加密，理论分析验证了方案的可行性。

Abstract: The secure transmission of the power information data, especially the international business data, determines the safety of the entire grid network. The unconditional security of quantum communication technology can greatly improve the security of the grid network and provide the detectability of eavesdropping. We propose a secure scheme for the international business data transmission in the grid network based on measurement-device-independent quantum key distribution protocol, where a plug & play struture is adoptd due to the characteristics of the international business data transmisssion. The scheme includes three parts, such as, the control & measure center, the extranet international business zone and the overseas transmission front area. the control & measure center is in charge of the generation of light pulse and the Bell measurements. The extranet international business zone and the overseas transmission front area are connected via virtual private network (VPN) to encryt data. The feasibility of the proposed scheme is verified by theoretical analysis.
