网络和通信技术的发展,使人们对无线通信的需求越来越高,短程、低速、廉价的无线通信技术正成为关注的焦点。目前一种新的无线通信技术引起了人们的关注,这就是所谓的“ZigBee”技术。为此,本文首先讨论了Zigbee无线传感器网络安全结构,接着分析了Zigbee无线传感器网络网络层和安全层,最后研究了Zigbee无线传感器网络安全密钥。因此本文具有深刻的理论意义和广泛的实际应用价值。 With the development of network and communication technologies, the demand for wireless communication is getting higher and higher. Short-range, low-speed and low-cost wireless communication technologies are becoming the focus of attention. Currently a new wireless communication technology has aroused people’s attention, which is the so-called “ZigBee” technology. Therefore, this paper first discusses the security architecture of Zigbee WSN, then analyzes the network layer and security layer of Zigbee WSN, and finally studies the security key of Zigbee WSN. Therefore, this article has profound theoretical significance and a wide range of practical application value.
