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
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.
This research proposes a combination of Quantum Key Distribution (QKD) based on the BB84 protocol with Improved Logistic Map (ILM) to improve data transmission security. This method integrates quantum key formation from BB84 with ILM encryption. This combination creates an additional layer of security, where by default, the operation on BB84 is only XOR-substitution, with the addition of ILM creating a permutation operation on quantum keys. Experiments are measured with several quantum measurements such as Quantum Bit Error Rate (QBER), Polarization Error Rate (PER), Quantum Fidelity (QF), Eavesdropping Detection (ED), and Entanglement-based detection (EDB), as well as classical cryptographic analysis such as Bit Error Ratio (BER), Entropy, Histogram Analysis, and Normalized Pixel Change Rate (NPCR) and Unified Average Changing Intensity (UACI). As a result, the proposed method obtained satisfactory results, especially perfect QF and BER, and EBD, which reached 0.999.
Quantum Cryptography evolves a technology which provides secure communication. In this work error correction and detection techniques are used to correct and detect the errors which occur either due to noise or attacks while transferring bits. The main objective of this paper is using error correction and detection techniques to correct and detect the error and analyze the comparison between BB84 Protocol, BB84 using Parity Bits and BB84 using Cyclic Redundancy Check for the number of bits match and mismatch frequency between sender and receiver. This methodology can be implemented using Mat lab simulator. It is very easy to analyze mathematically when compared to theoretical process.
Quantum communication is a rapidly evolving field that leverages quantum physics to enable secure and efficient information exchange. A cornerstone of quantum cryptography is Quantum Key Distribution (QKD), a secure key exchange mechanism that ensures the confidentiality of transmitted data by employing the no-cloning theorem and the uncertainty principle of quantum mechanics. This study explores key aspects of quantum networks and communication, including quantum states, QKD, and quantum cryptographic protocols, with a focus on photon polarization states and entangled qubits as fundamental building blocks of quantum information. Additionally, two well-established quantum cryptographic protocols, BB84 and E91, are analyzed for their principles and advantages in secure communication. However, challenges such as quantum state loss in communication channels hinder the long-distance transmission of quantum information. To address these issues, error detection, measurement, and correction techniques are investigated, with quantum error correction methods playing a crucial role in mitigating noise and imperfections, ensuring accurate quantum information transmission, and enhancing the overall efficiency of quantum communication systems. Beyond conventional networks, quantum communication holds vast potential for cybersecurity applications, paving the way for next-generation secure communication frameworks.
Quantum cryptography is the study of delivering secret communications across a quantum channel. Recently, Quantum Key Distribution (QKD) has been recognized as the most important breakthrough in quantum cryptography. This process facilitates two distant parties to share secure communications based on physical laws. The BB84 protocol was developed in 1984 and remains the most widely used among BB92, Ekert91, COW, and SARG04 protocols. However the practical security of QKD with imperfect devices have been widely discussed, and there are many ways to guarantee that generated key by QKD still provides unconditional security. This paper proposed a novel method that allows users to communicate while generating the secure keys as well as securing the transmission without any leakage of the data. In this approach sender will never reveal her basis, hence neither the receiver nor the intruder will get knowledge of the fundamental basis.Further to detect Eve, polynomial interpolation is also used as a key verification technique. In order to fully utilize the quantum computing capabilities provided by IBM quantum computers, the protocol is executed using the Qiskit backend for 45 qubits. This article discusses a plot of % error against alpha (strength of eavesdropping). As a result, different types of noise have been included, and the success probability of the desired key bits has been determined. Furthermore, the success probability under depolarizing noise is explained for different qubit counts.Last but not least, even when the applied noise is increased to maximum capacity, a 50% probability of successful key generation is still observed in an experiment.
