Modified auxiliary channel Diffie Hellman encrypted key exchange authentication protocol

Abstract

In the wireless network, security is a major concern. Bluetooth network is also highly vulnerable to attacks. This paper proposes a protocol called, Modified Auxiliary Channel Diffie Hellman Encrypted Key Exchange authentication Protocol (MACDHEKE), which authenticates the two previously unknown Bluetooth enabled devices. The user inputs a low security, low entropy pins and converts it into high security, high entropy shared key. It also authenticates the public key as being sent by the claimed sources or devices. It also analyzes how secure this protocol is against man in the middle attack as well as passive eavesdropping. © 2011 Springer-Verlag.
