Enhancing Bluetooth Authentication Using Diffie Hellman Algorithm
Bluetooth is a technology for connecting devices wirelessly to achieve data transfer at the rate of 720 kbps within a range of 10 to 100 meters. In existing authentication procedure for Bluetooth networks, four levels of key generation viz initialization key, combination key, link key, encryption key were incorporated. Bluetooth devices have limited resources, so users need a small authentication procedure. The authors proposed a new authentication scheme for Bluetooth networks. They presented enhancement in the authentication procedure of Bluetooth by using Diffie-Hellman Algorithm. This novel authentication procedure acts as the countermeasure against SNARF attack by the introduction of Diffie-Hellman algorithm.
