网络控制系统的网络安全研究

Network Security Research of Networked Control System

基于网络控制系统(networkedcontrolsystem,NCS)的基本概念,分析了NCS网络安全体系结构和动态需求,讨论了确保NCS网络安全的各种安全机制,提出了自律分散NCS安全体系策略,指出了如何设计具有自律可控性和自律可协调性的NCS安全体系的思想方法,并给出了相应的模型结构。

Based on the basic concepts of networked control system （NCS）, analyzes architecture and dynamic requirements of network security of NCS, discusses security policies of network security of NCS, puts forward new design methods, which include autonomous decentralized security architecture of NCS,design security architecture of NCS with autonomous controllability and coordinability and model, and points out some problems that should be further studied by network security theory of NCS.
