Integration of quantum key distribution in EAP-TLS protocol used for wireless LAN authentication

Mohamed Elboukhari, Abdelmalek Azizi, Mostafa Azizi

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.

Secure true random number generator in WLAN/LAN

Alexander G. Chefranov, Seyed Masoud Alavi Abhari, Hooman Alavizadeh +1 more

Wireless networks need more security in comparison to the other networks due to their intrinsic vulnerabilities to possible attacks. It is expected that by using a distributed method for true random number generators (TRNG) in wireless sensor networks (WSN) and wireless LAN (WLAN) randomness quality of generated numbers can be enhanced. We analyze a protocol for a distributed TRNG named ScatterLight (L. R. Giuseppe, M. Fabrizio and O. Marco, 2011) for a WSN. After making some changes on ScatterLight structure and physical data sources, the Enhanced ScatterLight protocol is introduced; it provides secure and high qualified true random numbers. Thus, the quality of randomness of obtained random numbers using National Institute of Standards and Technology tests is evaluated. Finally, by analyzing the results, it can be conducted that Enhanced ScatterLight protocol in comparisons with ScatterLight protocol in WLAN and LAN provides 60% and 53% better randomness quality respectively, while the performance is equal in both protocols.

Secrecy Capacity of Wireless LAN

Ryuzou Nishi, Yoshiaki Hori, Kouichi Sakurai

We address secure secret key distribution in wireless communication systems. There is the secrecy capacity concept that it can distribute information which the third parties can not eavesdrop because of the noise over the distribution channel. Then, we address secure secret key distribution in wireless communication systems using secrecy capacity concept. Wireless channel is noisier compared with wired channel. Specifically, we investigate about wiretap channel coding that it can implement in the existing wireless LAN systems. We have investigated the coding parameters and the conditions that it can implement.
