Security of data is one of the most important factors to take into account while elaborating any information system, especially when the information is transmitted over a wireless network like one of a company, a factory, a campus, or more importantly a battlefield. In those cases information becomes much more sensitive and must be secured via encryption algorithm. Whether the encryption is done using symmetric or asymmetric algorithm we have to deal with the main problem of key distribution. Quantum mechanics provide a new paradigm that can address effectively the classical problem of key distribution. The main idea of this work is about how to integrate the QKD (Quantum Key Distribution) in the IEEE 802.11i standard to improve the security of data transmitted over a wireless network, by enhancing the encryption key distribution phase.

User's mobility is increasing with the height level of mobility that the mobile networks offer. The information transmitted from A to B in a network has to be secured from any eavesdropping, so the main solution used is the cryptography. Nevertheless, the classical cryptography suffers from some limits that make it vulnerable in front of some kind of attacks like "attack by dictionary" or "exhaustive attack". In the other hand, the miniaturisation in processor industry (Moor's law) causes interferences. For that purpose and other new field appear to overcome that kind of problem. That is "Quantum cryptography". In the present paper we will present an enhanced proposition of integration the QKD in the 802.11i.
Abstract — There are a large variety of kinds of mobile wireless networks, Wi-Fi, based on the IEEE 802.11 standard, is a wireless local area network, mainly used in offices and campus at universities or in meeting rooms. For such limited coverage area, IEEE 802.11 standard may be observed as building oriented environment, which potentially offers a chance to let quantum key distribution (QKD) play a role in the security of wireless communications. In fact, secured data transmission is one of the prime aspects of wireless networks as they are much more vulnerable to security attacks. We can explore the possibility of using Quantum Key Distribution (QKD) for authentication and data encryption for IEEE 802.11 standard. Quantum key distribution is based on the laws of quantum physics which ensure that nobody can measure a state of an arbitrary polarized photon carrying information without introducing disturbances which will be detected by the legitimate user. In the new protocol (BB84) the existing 4-way handshake of IEEE 802.11 has been replaced with the QKD based 4-phase handshake. In the BB84 protocol each photons carry only one bits. So to improve the efficiency in Efficient High Capacity Quantum Cryptography based Key Distribution in WI-FI Network each photons carry two bits. The channels used in the QKD are quantum channel and classical channel. The polarized photons are transmitted through the quantum channel and the classical channel deals with recovering identical secrete keys at both ends. The classical channel comprises of four stages, namely Sifting, Error Estimation, Reconciliation and Privacy Amplification. The Quantum Bit Error Rate (QBER) is the measurement of the error probability in the key distributed via the quantum channel. This value allows the users to
It is well known that wireless networks have become one of the most important part used communication systems, in particular for ubiquitous computing. However, providing secure communication for wireless networks has become one of the prime concerns. Quantum cryptography, namely quantum key distribution (QKD), offers the promise of unconditional security. In this paper, we shall extend our previous research work to a new method of integrating quantum cryptography for key distribution in 802.11 wireless networks. Our contributions, based on our previous results [1], are as follows: (a) We shall show how QKD can be used in IEEE 802.11 wireless networks to securely distribute the keys. (b) We shall introduce a method that take the advantage of mutual authentication features offered by some EAP variants of 802.1X port-based network access control. (c) finally, we present a new code called quantum message integrity code (Q-MIC) which provides mutual authentication between the two communication parties and its implementation.
Most of our social activities, financial transactions, and other sensitive activities take place online. These transactions are subject to the risk of being intercepted by malicious individuals or groups. The channels that carry this information use a set of specifications called 802.11 and 802.11x standards, created by IEEE for WLAN technologies. Unfortunately, these standards are not the most secure and use the WEP (Wired Equivalent Privacy) protocol which is not well designed and does not hold up to today's methods of network penetration. In this paper we discuss the application of quantum cryptography as a way of creating encryption keys for wireless and mobile environments, which results in a secure solution to the weaknesses of the IEEE 802.11 standards and WEP protocol.
