Application of Group Key Agreement Based on Authenticated Diffie-Hellman for Bluetooth Piconet

Through the analysis of the characteristics of Bluetooth piconet and Bluetooth's security architecture, this paper gives out a scheme of group key agreement based on Diffie-Hellman key agreement protocol. It affords a method that nodes can authenticate each other in the Bluetooth piconet and defeat threats derived from Bluetooth link-level. In the last place, the feasibility of the scheme is verified.
