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.

For such limited coverage area, IEEE 802.11 standard is building- oriented environment, which potentially offers a chance to let quantum key distribution (QKD) play a role in the wireless communication. In fact, secured data transmission is one of the prime aspects of wireless networks as they are much more vulnerable to security attacks. In this paper, we explore the possibility of using quantum key distribution (QKD) for authentication and data encryption for IEEE 802.11 standard. It will focus on some basic concept that how QKD merges the wireless communication, in particular the IEEE 802.11 standard. The software implementation of the first two phases of QKD, namely (a) raw key extraction and (b) error estimation, will be carefully investigated in this paper. A TCP/IP based client-server concept has been extended to the implement the communication between two users in C++ language.

The goal of cryptography is to encode data in such a way that no one can decode it unless they are the intended recipient. With the emergence of quantum computing, classical cryptography is not reliable enough to protect sensitive information. Nevertheless, there are alternatives. Quantum Key Distribution (QKD) is a method to secure communication based on the laws of quantum physics. Due to being impossible to measure the quantum state of a system without disturbing it, QKD provides a way to communicate between two parties while being, in theory, immune to eavesdropping. In this work, a free-space high-speed QKD setup is proposed, with the objective of implementing the polarization three-state one-decoy variant of the BB84 protocol. An assessment of the best type of laser diode to use for free-space QKD is made between several options. The system’s performance was assessed, incorporating a quantitative analysis of system losses and an estimation of the number of photons traversing the quantum channel. The system achieved a Quantum Bit Error Rate (QBER) of 1.58% for the Z basis and 1.46% for the X basis, for an average reception of two photons per pulse. Preliminary QBER measurements were also undertaken in the context of Quantum Keyless Private Communication protocols, focusing on the average number of photons per pulse.
Quantum key distribution is a new method in key distribution system in cryptography used to transmit secret key between two legitimate parties. This method is an invention in quantum cryptography as part of quantum mechanics which solves the key distribution's problem in cryptosystem by providing a secure communication channel between two parties with absolute security guaranteed by the laws of physics. Communication not only occurred in wired medium but also in wireless medium. WLAN as a wireless medium are much noisier and less reliable in general than wired mediums. This type of noise will generate different numbers of key length and also different level of error rate estimation. Thus, how much secure of the data could be protected on wireless communication? In this study, we implement BB84 protocol on 802.11i wireless local area network (WLAN) to show the affect of noise and eavesdropper could make the data transmission is much secure in wireless medium. In our study shows that implementation of BB84 in 802.11i is able to secure the key distribution from being stealing by the third party.
A quantum key distribution (QKD) system produced shared secret key and transmitted the key between the sender and receiver in a highly secured transmission. QKD uses the fundamental of quantum properties of a single photon to provide a secured communication channel with absolute security guaranteed by the laws of physics. This research has developed a simulator software for BB84 and B92 protocols which implemented both protocols in 802.11i WLAN environment. The parameters used for this research are with attack and without attack, where measured by three measurements for both protocols which are final key length, expected key length by eavesdropper and error rate estimation. The 802.11i WLAN is consider as insecure because the tendency to be intercepted by intruders is high. Furthermore, the interference from other consumer devices such as cordless phone and microwave can contribute to degradation of WLAN performance. This type of noise can generate different numbers of final key length and different levels of error rate estimation. Thus, the level of the error rate estimation determined the secrecy of the secret key. The discussion of security issue between BB84 and B92 protocols also discussed in terms of secrecy and strength of the secret key between both protocols in 802.11i WLAN.
