摘　　要：针对国内核电厂反应堆保护系统(RPS)DCS平台研发和工程实施过程中的信息安全进行了研究,采用信息安全分级方案、区位模型,以及攻击树建模方法,对RPS进行级别和区位设定,并建立RPS攻击树模型,分析可能的攻击途径。提出了系统化的信息安全分析方法和信息安全措施,可供核电厂RPS系统平台研发、工程实施和运行维护等项目参考。In the process of DCS platform developing and engineering implementation of nuclear power plant Reactor Protection System（RPS） , to enhance Cyber security of RPS, RPS access paths were analyzed, and security level and zone were set by graded approach and zone model. The attack tree model for RPS was established to analyze the attack ways. The paper put forward systematic cyber security analysis method and countermeasures mentioned which can be referenced by the project of RPS platform developing, engineering implementation and operating maintenance.
