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
