The requirement of efficient security protocols to protect confidential information from ever evolving cyber threat has been highlighted by the fast implementation of wireless sensor network (WSN) in numerous important domains, including healthcare monitoring, environmental surveillance and military operations. Despite their feasibility, traditional cryptographic approaches are utilized behind the computing capability of recent attackers, including the possibility of future quantum computer attacks. In order to revolutionize WSN security, this study proposes utilizing quantum cryptography and other concepts from quantum computing into the existing framework. This research leads to develop a communication protocol that is extremely safe and against the cyber-attacks. This protocol utilizes the quantum key distribution (QKD) to protect data and granting its confidential. In addition to improving security, the new architectures begin with change that makes WSN more capable of dependable and secure operations in environment where data protection is essential. A complete framework for protecting WSNs from new cyber threats in the future while keeping data transmissions and efficient process with reliability is discussed in this study. This proposed method enhances the dependencies in WSN installation across various industries, which is important for applications that need strong security measures. Evaluation results shows that the proposed method outperformed all existing methods in terms of relevant metrics.

Finally, the study delineates future prospects and potential research directions, emphasizing the need for interdisciplinary collaboration to overcome existing limitations and fully realize the potential of QKD in enhancing wireless network security.
Data that is transient over an unsecured wireless network is always susceptible to being intercepted by anyone within the range of the wireless signal.Hence providing secure communication to keep the user's information and devices safe when connected wirelessly has become one of the major concerns.Quantum cryptography provides a solution towards absolute communication security over the network by encoding information as polarized photons, which can be sent through the air.This paper explores on the aspect of application of quantum cryptography in wireless networks.In this paper we present a methodology for integrating quantum cryptography and security of IEEE 802.11 wireless networks in terms of distribution of the encryption keys.
Quantum Key Distribution (QKD) is used in Quantum Cryptographic Systems to exchange secret key between parties who need to communicate secretly. Such a key can be used with a symmetric encryption schemes to establish a secure communication. Until recently, QKD is possible using optical fiber over few tens of kilometers but not more due to single photons getting absorbed by the fiber. There are no commercial wireless quantum crypto products yet, but QKD will soon be used in wireless medium from satellite to the earth so we could get 10,000 miles. But wireless medium brings its own problems. The energy transmitted via a wireless link spreads out, leading to higher and varying transmission losses, ambient daylight, or even light from the moon at night couple into the receiver, leading to a higher error rate. Interference from other photon sources air with clouds, dust and unsettled conditions creates intervention. In this paper, different techniques for communication in Quantum Cryptography using wireless networking infrastructure are discussed.
Today‟s wireless network has become one of the most important communication medium. However, providing secure communication for wireless network has become the challenging issues at present days. In present communication system, traditional cryptography was used for secure communication. It has more computational complexity and intruder may easily retrieve the encrypted messages. To overcome this complexity we aim to design a new protocol using quantum bits for enhancing the security. Quantum mechanics defines structure and behavior of quantum bits (i.e.) often called Qubits and it is thousand times faster than traditional one. A traditional computer system uses two bits 0 (or) 1. In quantum system uses Qubits that is normally represented mathematically by vectors such as |0>, |1> as two states, and four bases |H>, |V>, |R>, |L>. By this quantum cryptography method two parties may generate secret cryptographic key known as checkbits which are generated using static quantum channel. Two channels namely public and hidden channels are used to transfer data through secured mode without encryption. By using hidden channel concept in quantum mechanics, secure transmission of data without encryption can be done.
Recent misuse of wireless internet by terrorists has increased the need for security in the same. With ever growing technology both cryptographers, who encrypt messages, and cryptanalysts, who break those codes, have equal opportunities and facilities. Quantum Cryptography seems to be a promising solution providing absolute security in such communications. Its works by identifying the threats and combats them by using basic laws of Quantum Physics. Since the first proposition on quantum key distribution protocol appeared in 1984, research on quantum cryptography has been growing rapidly. Experiments of quantum key distribution have been realized for optical and free-space environments [1, 2, 3, and 4]. In fiber networks, some products have been commercialized to provide a turnkey service for widely used encryption algorithms [5], In section 2 and 3 we analyze the authentication and key management in 802.11 networks and in section 4 we are giving the introduction of Quantum Cryptography with QKD and in section 5 we are integrating quantum technique for the distribution of encryption keys in 802.11 wireless networks.
