摘　　要：以典型核安全级分布式控制系统(DCS)为例,应用故障模式与脆弱性影响分析(FMVEA)技术评估功能安全与信息安全的兼容性,并采用事件树和风险分析相结合的方法给出功能安全与信息安全协同解决方案,最终得到核安全级DCS功能安全与信息安全一体化防护措施。一体化防护措施实践结果表明,应用权衡技术得到信息安全措施,可以较好地兼容原有功能安全措施。因此,本研究建立的权衡技术可以应用于核安全级DCS信息安全设计工作。Taking the typical nuclear safety class DCS as an example, the FMVEA technology is used to evaluate the compatibility between functional safety and cyber security. The combination of event tree and risk analysis is used to give functional safety and cyber security coordination solutions, and finally obtain the integrated protective measures of nuclear safety class DCS functional safety and cyber security. The results show that the application of trade-off technology to obtain the cyber security measures can be better compatible with the original functional safety measures. Therefore, the trade-off techniques established in this study can be applied to nuclear safety class DCS cyber security design work.
