Despite years of intensive research, the main deterrents of widely deploying secure communication between wireless nodes remains the cumbersome key setup process. In this paper, the authors address this problem and they introduce a novel security primitive that enables message authentication in wireless networks without the use of pre-established or pre-certified keys. Quantum cryptography utilizes the Quantum Physical Effects to offer completely secure communication even in the presence of an intruder who is assumed to possess infinite computational power and access to the communication channel. It overcomes the shortcomings of Classical Cryptography by not relying on the computational difficulty in breaking the key.
