An Authentication Mechanism Preventing Malicious Devices From Participating in ZigBee Network

Abstract

ZigBee, LR-WPAN's major technology. is based on IEEE 802.15.4 specification and ZigBee Alliance to realize home network environment. While basic security services are provided, there is a lack of more advanced techniques which are indispensable in modern ZigBee application. But, in ZigBee network. ZigBee coordinator progresses key exchange protocol without device authentication when initial device joined in ZigBee network. It can cause various kinds of attacks through malicious devices within ZigBee network. In this paper, we propose an authentication mechanism preventing malicious devices from participating in ZigBee network. The proposed mechanism provides authentication for initial device with ZigBee coordinator which 'serves as authentication server.
