中文摘要：

基于工业以太网的控制系统，既与物理世界相连，又与信息世界相连，所以系统安全需要同时考虑功能安全和信息安全。协议栈是基于工业以太网的控制系统实现网络互连的核心，结合Cortex-A8的架构特性，设计了综合功能安全和信息安全的安全协议栈。利用基于Cortex-A8的AM3359微处理器的工业通信子系统、高速处理能力和低功耗，实现了工业以太网安全协议栈。实验结果表明，在故障注入和模拟入侵的情况下，安全协议栈能有效地减小故障概率和入侵成功概率。

英文摘要：

The control system is based on the industrial Ethernet connects with the physical world, and also connects with the information world, so security of system needs to consider both function security and information security. The protocol stack is the core to make the interconnection of the control system based on the industrial Ethernet, and a safe protocol stack which synthesizes function security and information security is designed with the architectural characteristic of Cortex-A8. The industrial communication subsystem, the high-speed process capacity and the low-power consumption of the AM3359 microprocessor based on Cortex-A8 are used to implement the security protocol stack of the industrial Ethernet. The experimental results indicate that the safe protocol stack has decreased the fault probability and invasion probability of success efficiently when the industrial Ethernet is under fault injection and simulation invasion.
