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.
It is the fact that wireless local area networks are increasingly deployed by businesses, government and SOHO users as they offer many advantages to its customers with mobility, flexibility, convenience etc. It opened a wide range of new commercial areas for hardware vendors, at low cost. This justifies why wireless networks have become one of the most widely used communication systems in the world. However, since there are no boundaries in wireless networks, they are vulnerable to security threats than wired networks. Therefore, providing secure communication for wireless networks has become one of the prime concerns. Quantum cryptography, to be precise, Quantum Key Distribution (QKD), offers the promise of unconditional security. In this paper, we extend our previous research work of how QKD can be used in IEEE 802.11 wireless networks to ensure secure key distribution. Our contributions in this paper are as follows: (1) We discussed how QKD can be used in IEEE 802.11 wireless networks to securely distribute the keys. (2) We use new protocol QKD. (3) We introduced a method that take the advantage of mutual authentication features offered by some EAP variants of 802.1X Port-Based Network Access Control. (4) Finally, we present a new code called Quantum Message Integrity Code (Q-MIC) which provides mutual authentication between the two communication parties. Also experimental results are presented with Simulink Model.

Every attempt to access to the Internet through a Web browser, email sent, VPN connection, VoIP call, instant message or other use of telecommunications systems involves cryptographic techniques. The most commonly applied technique is asymmetric cryptography, which is generally executed in the background without the user even being aware. It establishes a cryptographic code based on the computational complexity of mathematical problems. However, this type of cryptography, which is widely used in today’s telecommunications systems, is under threat as electronics and computing rapidly develop. The development of fifth-generation cellular networks (5G) is gaining momentum, and given its wide field of application, security requires special attention. This is especially true faced with the development of quantum computers. One solution to this security challenge is to use more advanced techniques to establish cryptographic keys that are not susceptible to attack. An essential part of quantum cryptography, Quantum Key Distribution (QKD) uses the principles of quantum physics to establish and distribute symmetric cryptographic keys between two geographically distant users. QKD establishes information-theoretically secure cryptographic keys that are resistant to eavesdropping when they are created. In this paper, we survey the security challenges and approaches in 5G networks concerning network protocols, interfaces and management organizations. We begin by examining the fundamentals of QKD and discuss the creation of QKD networks and their applications. We then outline QKD network architecture and its components and standards, following with a summary of QKD and post-quantum key distribution techniques and approaches for its integration into existing security frameworks such as VPNs (IPsec and MACsec). We also discuss the requirements, architecture and methods for implementing the FPGA-based encryptors needed to execute cryptographic algorithms with security keys. We discuss the performance and technologies of post-quantum cryptography, and finally, examine reported 5G demonstrations which have used quantum technologies, highlighting future research directions.

Quantum cryptography is a promising solution towards absolute security in long term cryptosystems. 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. In this paper, we analyze the interests of using quantum cryptography in 802.11 wireless networks, and propose a scheme integrating quantum cryptography in 802.11i security mechanisms for the distribution of the encryption keys. The use of an apparatus network to provide alternative line-of-sight paths is also discussed.
