中文摘要：

物联网环境下，工业以太网和实时以太网的控制回路容易被利用进行恶意攻击，造成物理世界中重大的安全事故；通过分析物联网环境下控制系统的工作原理，提出物联网环境下的通用控制系统模型IoTC，并以该模型为基础，讨论系统中可能面临的各种干扰因素；针对这些干扰因素，提出一种通用控制系统安全模型S-IoTC，该模型通过在干扰处加入安全认证模块以保障系统安全性；最后就安全模型S-IoTC的组成部分、安全定理以及典型的实现过程进行了阐述。

英文摘要：

In Internet of things, the control loop of industrial Ethernet and real-time Ethernet is easily exploited by hackers for malicious attacks, causing serious security incidents in the physical world; a universal control system model （IoTC） was put forward by analysing the working principle of the control system in loT, on which some disturbing factors the system faces were discussed; for the disturbing factors in the system, one universal control system security model （S-IoTC） was given, adding security authentication module in responding disturbing factor to achieve secure system; the components, safety justice and typical realization process of S-IoTC were also described in detail at last.
