Scalable Wireless Network Security for Bluetooth in Global Collaborative Environment

Ubiquitous revolution is widely implemented around the world, innovative changes in mobile information environment provides high quality to meet many different users´ demanding requirements. In particular, as computers, household appliances, communications and broadcasting are converged into a digital media based on high speed communication network and digital convergence generating new value is performed, various mobile communication technologies have been researched. Short-distance mobile communication technologies can create user-oriented networks and be applied to real lives, drawing the public´s attention. If, however, short-distance mobile communication is connected to various devices to provide services, increasing numbers of devices and problems related to security and safety must be considered. Therefore, safe and effective configuration schemes to ensure scalability as well as management of the existing simple networks must be studied to create a convergence environment. Therefore, this paper aims to propose the mutual authentication and session keys can be used to manage slaves safely and reliably based on existing scalable bluetooth piconet[HSI 2005]. As a result, improved network configuration and security can be ensured by suggesting bridge setting to provide secure communication among masters as well as security of the expanded network.
