基于Zigbee的WPAN安全性研究和分析

Study and Analysis of WPAN Security based on Zigbee

近年来随着半导体技术、微系统技术和计算技术的飞速发展,无线个域网的研究和应用在世界各地迅速发展,随之而来的是对其安全性的高要求,因此安全性成为基于Zigbee的无线个域网(WPAN,Wireless Personal-Area Network)广泛应用和发展的瓶颈。通过分析Zigbee的协议栈架构及其安全体系、从安全模式、安全服务、安全方案规范和网络密钥管理等方面对基于Zigbee的WPAN安全性进行细致的分析,特别对Zigbee在认证和加密方面存在的问题和未来的发展进行了分析和总结。

With rapid development of semiconductor technology,microsystem technology and computing technology,WPAN is energetically studied and widely applied,thus resulting in the high requirement for its security.So the security of Zigbee-based WPAN becomes the bottleneck for its wide application and rapid development.The paper first analyzes the Zigbee protocol stack framework and safety system,and from safety mode,safety service,safety strategy standard and network key management,discusses in detail the security of Zigbee-based WPAN,particularly analyzes and summarizes the existing problems and future development in the aspects of Zigbee authentication and encryption.
