变电站软件版本安全管控与溯源

Security Management and Traceability of Substation Software Versions

目前,变电站自动化设备软件与配置没有经过严格的检测与验证也没有集中统一管理,给变电站自动化系统的安全运维带来了极大风险。通过对网省/地三级自动化运维管理系统体系架构设计解决设备软件等软件版本的集中统一管理、管控;基于数字认证技术与国密算法对变电站内设备软件进行数字签名、验证,实现软件版本完整与可追溯。其核心内容及创新点包括:通过设计一套网省/地三级自动化运维管理系统来实现变电站设备软件、配置文件的集中统一管理、管控;采用基于数字认证技术与国密算法实现设备软件、配置文件的逐级数字签名与验证,解决软件版本在各流程环节的完整性与可追溯性问题。

At present,the software and configuration of substation automation equipment have not undergone rigorous testing and verification or centralized management,which has brought great risks to the safe operation and maintenance of substation automation systems.A three-level(network-provincial-local)automated operation and maintenance management system architecture is designed in this paper to realize the centralized and unified management and control of equipment software and other software versions.Based on the digital authentication technology and national secret algorithm,the integrity and traceability of software versions are achieved through digital signature and verification of equipment software in substations.The key contents and innovation in this paper include:(1)the centralized and unified management and control of the substation equipment software and configuration files are achieved through designing a three-level automated operation and maintenance management system;(2)the integrity and traceability of software versions in each process is realized through step-by-step digital signature and verification of equipment software and configuration files using digital authentication technology and national encryption algorithm.
