基于信息物理融合的网络控制系统安全研究策略

The Security Research Strategy of Network Control System Based on Cyber-Physical Fusion

信息物理融合系统(CPS)是工业控制系统安全的本质特征,其安全技术涉及网络技术、控制理论、信息安全等多个学科。网络控制系统作为一类典型的工业控制系统,其信息安全问题具有很强的代表性。NCS安全技术研究急需解决的难点问题包括:现场总线安全协议架构、基于信息物理融合的入侵检测、基于信誉的系统级信任管理等。信息物理融合的思想应该成为NCS安全研究策略的核心。

The Cyber-Physical System （CPS） is the essential feature of the industrial control system security, including the security of network technology, control theory, information security, etc. As a kind of typical industrial control system, the information security issues of network control system have a strong representative. The difficult issues which need to be resolved include： the field bus security protocol architecture, the intrusion detection based on cyber- physical technology, the system-level trust management based on credit. The thought of cyber-physical fusion should become the core of the research on network control system security .
