Extensive studies have been undertaken on quantum cryptography, which offers unconditionally secure communication based on quantum mechanics, since it was noted that quantum computers could break public key cryptosystems based on number theory. Now there is a strong need of research to exploit this technology in the existing communication networks. While the use of quantum cryptography in fiber optical networks gets significant advances, research on the application of quantum cryptography in mobile wireless network is still premature. There are a large variety of kinds of mobile wireless networks, Wi-Fi, based on the IEEE 802.11 standard, is wireless local area network and due to the limited coverage area, this environment potentially offers a chance to let quantum key distribution (QKD) play a role in the wireless communication. In this paper, we propose a technique of integrating quantum cryptography in 802.11 to provide a secure service of authentication. It is based on integrating QKD in the EAP-TLS conversation to enhance the security of the authentication process.

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. Key distribution is the problem of classical cryptography algorithm, and tends to provide safe channel to transport key. Quantum cryptography could distribute key in quantum channel. Eavesdropper can not access to key on quantum channel. If Eve attack on quantum channel QBER increases and she is detected. While the application of quantum cryptography in fiber network has significant advances, research on the application of quantum cryptography in mobile networks is still premature. In this paper, we analyze the interests of using quantum technique for the distribution of encryption keys in 802.11 wireless networks. We also propose a scheme for the combination of quantum cryptography and 802.11i security mechanisms for the establishment of the PTK (Pairwise Transient Key).

Post quantum is a general name to all the techniques which are safe against the quantum computer attack. The wireless network is one of the most important means of communication. Wireless network security is a top priority. Wireless networks use conventional cryptography, which has various flaws, whereas quantum cryptography claims to be completely secure. It wasn't long after quantum computers became operational that people began to think about new ways to secure electronic communications. After considering all of the weaknesses in conventional cryptosystems, individuals began to look for new ways to secure electronic communications. Traditional cryptography has many problems, but quantum cryptography addresses nearly all of them.
