A Bypassing Security Model for Anonymous Bluetooth Peers
Hahnsang Kim, Walid Dabbous, Hossam Afifi · 2005
Bluetooth technology provides conveniences ranging from simply substituting for wires of electrical household products to constructing home network systems. Providing Bluetooth-technology-based services in public raises security issues in providing a secure Bluetooth link for unknown Bluetooth peers. In this paper, we present a bypassing security model for protecting communications between anonymous Bluetooth peers via wireless local area network (WLAN) and authentication authorization and accounting (AAA) technologies. Our bypassing security model is composed of the Bluetooth peer authentication, the Bluetooth key negotiation, and the link key generation. It brings a cost-effective realization in conjunction with standard technologies and is suitable for large-scale service providing systems by relying on the infrastructure network. In contrast to a certificate-based Di0flie-Hellman method that requires computation-intensive cryptographic functions, our model performs faster on power-limited devices.
