摘　　要：在工业控制系统面临的网络攻击活动日益频繁的形势下,将基于密码的信息安全技术用于工业远程实时控制系统中是一项意义重大的技术创新。先讨论目前工业控制系统面临的安全威胁,指出了工业控制系统的信息安全目标,然后分析如何应用基于密码的信息安全技术防护这些威胁。同时,提出两种在控制站和受控设备之间建立可靠、可信的控制通信信道的加密模型,其实际应用为密码技术在工业控制系统信息安全中的应用提供了参考。Nowadays,the industrial control systems are facing the situation of network attacks become more frequently,thus applying cryptography based information security technology in industrial remote and real time control systems is very important technologic innovation.The security threats of which industrial control systems facing are discussed first; and the target of information security for industrial control systems are pointed out,then the measures of applying cryptography based information security technologies to prevent these threads are analyzed. In addition,two types of the encryption models of establishing reliable and credible communication channel between control station and controlled equipment are proposed. The practical application of these models will be helpful to provide applicable reference for applying cryptographic technology in information security of industrial control systems.
