The Research And Implementation Of Bluetooth Wireless Networks Security System

Bluetooth Technology is a kind of open specification for wireless data and voice. It bases on low cost short-range radio link, and it can build a wireless link for fixed and mobile device.After describing and analyzing the framework of Bluetooth system, this paper discusses its wireless access in detail. The Bluetooth technology provides peer-to-peer communications over short distances. WLAN over Bluetooth is a temporary autonomic system which is a distributed network without any central administration. Since the nodes in a network can serve as both routers and hosts, Bluetooth wireless access is different from other WLAN technologies. After comparing several popular WLAN technologies nowadays, this paper presents these technologies will inosculate and points out a good future of Bluetooth.In order to provide usage protection and information confidentiality, the system has to provide security measures both at the link layer and the application layer. Security system protects communication by using measures such as key management, authentication, encryption and entities such as unique Bluetooth address, different link key and encryption key, etc.This paper analyzes main framework and operation process of Bluetooth wireless networks security system, and achieves its DEMO model on software. After suggesting a series of improvements in theory, this paper introduces chaos theory and one-way hash function into the DEMO which will be improved in experiment. It may be useful to research and development of the future Bluetooth wireless networks security system.
