Abstract

In a growing world of users who seek services of wireless networks for their day-to-day activities, providing secured communication has become a prime and serious concern. But wireless communications are vulnerable to security attacks. Out of many wireless networks, WiFi, known as IEEE 802.11, has attracted millions of users worldwide. Our previous research work has demonstrated a quantum cryptography based approach to distribute the secrete key in 802.11 networks. In the current paper, we attempt to focus on the simulations and the analysis of our implementation of the experimental results about the key distribution solutions to confirm our previous research results.

Wireless technology is rapidly evolving, and is playing an important role in the lives of people throughout the world. Due to the nature of open guide medium of wireless communications, it is possible for an adversary to snoop on confidential communications or modify them to gain access to the wireless networks more easily than with wired networks, which has been drawing great attentions. In this paper, we focus on improving the security of IEEE 802.11 networks through secure key distribution using Quantum Key Distribution (QKD) which offer unconditional security between two communication parties. In our previous research work, we have demonstrated a novel protocol using quantum cryptography for secure key distribution in IEEE 802.11 networks. In our current paper, we analysis the experimental results we obtained in our previous research works, which will be focusing on the reconciliation phase of this protocol.

Effective Key Authentication for Ieee 802.11 Networks using Quantum Cryptography

G. Murali, Ramendra Prasad, Valli Madhavi

Wireless networks are growing tremendously and their applications are also becoming prominent from day to day [5]. As wireless applications are becoming popular, the security issues [3] related to 802.11 are also has a great consideration. These are gaining popularity because of their mobility, low cost, convenience and easy establishment. Among many wireless networks, the 802.11 has a large amount of users than compared to the others globally. The key which is used for encrypting and decrypting purpose plays a crucial role between users. As the wireless networks are open guide medium of wireless communications [3] , there is possibility for hackers to snoop on confidential communications. There is a chance to modify them to gain the access to the wireless networks more easily. In the key distribution of quantum is done according to Heisenberg uncertainty Principle. We will be focusing on Quantum Key Distribution which offers a high level security between two communication parties with the help of novel protocol. We will also focusing on the analysis of experimental results focusing on the different phases of protocol.

Secure Communication in 802.11 Networks with a Novel Protocol Using Quantum Cryptography

Xu Guang Huang, Shirantha Wijesekera, Dharmendra Kumar Sharma

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.
