基于網(wǎng)絡(luò)控制系統(tǒng)(networked control system, NCS)的基本概念，分析了NCS 網(wǎng)絡(luò)安全體系結(jié)構(gòu)和動(dòng)態(tài)需求，討論了確保NCS 網(wǎng)絡(luò)安全的各種安全機(jī)制，提出了自律分散NCS 安全體系策略，指出了如何設(shè)計(jì)具有自律可控性和自律可協(xié)調(diào)性的NCS 安全體系的思想方法，并給出了相應(yīng)的模型結(jié)構(gòu)。

Abstract: 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.
Keywords: networked control system (NCS)，network security theory，autonomous decentralized， architecture models
