摘　　要：计算机技术和网络技术的发展,促进了控制系统产品的更新,数字化控制系统(DCS)逐渐替代模拟系统,但是数字化系统的广泛应用同时也带来了更多信息安全的问题,身份认证便是其中之一。身份认证作为整个信息安全体系的基础,越来越引起人们的高度重视,基于智能卡、口令和生物特征组合的多因素身份认证技术成为当前研究的热点[1]。针对核电厂安全级DCS工程师站的身份认证进行分析,对工程师站进行全生命周期的危害分析,提出适用于核电厂安全级DCS工程师站的身份认证方式。The development of computer technology and network technology promotes the updating of control system products. Digital control systems gradually replace simulation systems, however, the wide application of digital control system brings more information security problems, identity authentication is one of them.As the basis of the whole information security system, identity authentication has attracted more and more attention.Multi-factor identity authentication technologies based on combination of smart card, password and biometric has become a hot spot of current research.This paper analyses the identity authentication of 1E DCS engineering station in nuclear power plants, analyses the hazards of the whole life cycle of it, and puts forward the suitable identity authentication method on1E DCS engineering station of nuclear power plants.
