This paper is the development of new pairing protocol for secure data communication using Bluetooth technology. An improved pairing protocol has been developed by adopting the Diffie-Hellman Key Exchange protocol in computing the shared secret value of both parties. MD5 and a light-weight encryption algorithm, the Hummingbird-2, were then employed to further strengthen the pairing mechanism and at the same time, making it suitable for devices that has limited processing power and memory. The proposed protocol is expected to provide Bluetooth devices a greater security against eaves-dropping and man-in-the-middle attacks.
