Application and Analysis of ZigBee Security Services Specification

ZigBee is a wireless technology developed as an open global standard. With the application of wireless sensor networks, many applications not only have low-power, low-complexity and cost-effective, but also should have high confidentiality. So the research of the security of ZigBee is becoming very important. Based on the ZigBee network protocol stack structure, in this paper, we mainly discuss the ZigBee data transmission security services, the encryption techniques, security key, the trust center, secured Frames Format and security Level. At last we introduce the security application in the ZigBee application layer.
