针对基于数字证书签名体制的电力系统信息交换安全认证体系,分别设计了PCI密码卡和以ARM微处理器为核心的嵌入式密码计算模块,通过嵌入密码计算模块或PCI密码卡,实现现有变电站设备与各信息交换主体通信的安全认证。密码计算采用国家密码管理委员会办公室指定的密码技术。
Aiming at the power system information exchange security authentication system based on digital certificate signature system, the PCI cryptographic card and the embedded cryptographic computation module based on ARM microprocessor are respectively designed. By embedding the cryptographic computation module or PCI cryptographic card, the existing substation Equipment and the main exchange of information exchange security certification. The password calculation uses the password technology specified by the office of the State Password Management Office.
