工业无线技术是满足工业应用高可靠、低能耗等特殊需求的一类无线传感器网络技术。针对WIA-PA(wireless net-works for industrial automation-process automation)工业无线网络的特点,分析了工业无线网络入侵检测的重要性,设计了一种基于全信道分析仪的分层WIA-PA网络入侵检测和安全数据处理架构,提出了一种适用于WIA-PA网络的分层入侵检测方法,在此基础上,设计并实现了基于WIA-PA的安全管理系统。测试表明,基于全信道分析仪的入侵分析系统能够有效检测网络入侵攻击,基于安全管理者的设备安全入网、密钥管理和安全服务能够在无线环境中得到较好的应用,有效地解决了工业无线网络内部资源受限的问题,提高了WIA-PA网络通信的安全性能。

Industrial wireless technology is a special kind of wireless sensor network technology. It is not only designed for the special needs of industrial applications, but also for high reliability and low energy consumption. In this paper, we first study the importance of intrusion detection for wireless industrial network. Subsequently, we propose a hierarchical intrusion detection system based on the all-channel analyzers and security management framework for the wireless networks for industrial automation-process automation （WIA-PA） network. Finally, we implement the security system for WIA-PA network. Test result shows that the scheme can detect the intrusion attack efficiently; the safe joining process and key management based on security manager could be used in the wireless environment well. The proposed system effectively solves the problem of limited internal resource in wireless industrial network, and prolongs the lifetime of the network.
