Nowadays, people's demands on wireless network are getting higher and higher. Security problem is becoming the focus that wireless networks pay attention to. This paper discusses the security structures of ZigBee in home automation system, analyzes the security of Medium Access Control (MAC) layer, Network (NWK) layer and Application (APL) layer. Moreover it analyzes the authentication and encryption in ZigBee technology completely, and proposes opinions for network security protection, solves the confidentiality, integrity and access control problem in network communication. This paper introduces the conceptual understanding and strategy of ZigBee IEEE 802.15.4 standard to be deployed in smart home environment. ZigBee technology offers a multi-hop communication capability for data transfer. For the last few years, we've witnessed a great expansion of remote control devices in our day-to-day life. Five years ago, infrared (IR) remotes for the television were the only such devices in our homes. One of the most promising HAN protocols is ZigBee, a software layer based on the IEEE 802.15.4 standard. Multi-hop communication will provide unlimited range of communication for the system as long as there are intermediate nodes that will pass the data from one node to another until it reaches the destination. And finally the zigbee communication protocol presents its potential deployment in smart home environment.
