Secure Connections in Bluetooth Scatternets

Bluetooth is a wireless networking technology specifically developed for Personal Area Networking and other short range applications. Bluetooth devices can be networked together by forming piconets of up to eight devices, where a single device is the master and the rest are slaves. These piconets can further be interconnected to create a scatternet. A scatternet is formed by allowing bridge nodes to operate in multiple piconets by interleaving their membership. These bridge nodes alternate between piconets by scheduling their participation during disjoint time-slots. Scatternet formation and routing are important problems for the future of Bluetooth. Another equally important issue is security. We describe how Bluetooth security is currently implemented and discuss a number of security attacks. We then describe two scatternet scenarios that warrant secure operation, and propose solutions that meet our security goals of confidentiality, availability, and integrity. A secure scatterne...
