Abstract:	As the fast development of Bluetooth networks and wireless communications, the mobile devices share information with each other easier than ever before. However, the handy communication technology accompanies privacy and security issues. Nowadays, a Bluetooth adopts peer-to-peer and Frequency Hopping Spread Spectrum (FHSS) mechanisms to avoid data reveal, but the malicious attacks collect the transmission data of the relay station for a long period of time and then can break into the system. In this study, we take a Piconet as a cube, and transform a Scatternet into a cluster (N-cube) structure. Subsequently, this study exploits the Elliptic Curve Diffie-Hellman (ECDH) [1] and the Conference Key (CK) schemes to perform session key agreements and secure data transmissions. The proposed scheme only needs a small key length 160-bit to achieve compatible security levels on 1024-bit Diffee-Hellman (DH) [2], and each node uses few CPU, memory and bandwidth to complete security operations. As a result, the proposed fault-tolerant routing algorithm with secure data transmissions can perform rapidly and efficiently, and is quite suited for Bluetooth networks with limited resources. ?
