Defence Against Man in Middle Attack in Secure Simple Pairing
Secure simple pairing has been adopted by Bluetooth version "Bluetooth 2.1+EDR (Enhanced Data Rate). It should be noted that for establishing Bluetooth connection that uses Diffie hellman public cryptography in its communication, SSP is a secure method. But it is still prone to attack regardless of the high security mechanism it provides, for example man in middle attack. In this paper, the authors provide a efficient method to prevent man in the middle attack. For real-time voice exchange and short range wireless data transmission in billion of devices and consumer electronics, Bluetooth is an affordable wireless class technology.
