The uses of computer communications networks technologies have increased the incidents of computer abuse. Because of these incidents, most organizations facing pressure to protect their assets. Most digital networks generally rely on modern cryptosystems to secure the confidentiality and integrity of traffic carried across the network. The current modern cryptosystems based on mathematical model introduce potential security holes related to technological progress of computing power, the key refresh rate and key expansion ratio, the most crucial parameters in the security of any cryptographic techniques. For that reason efforts have been made to establish new foundation for cryptography science in the computer communications networks. One of these efforts has led to the development of quantum cryptography technology, whose security relies on the laws of quantum mechanics [1,2,3,20, 24]. This research paper concentrates on quantum cryptography, and how this technology contributes to the network security. The scope of this research paper is to cover the weaknesses, and the security pitfalls in modern cryptography, fundamental concepts of quantum cryptography, the real - world application implementation of this technology, finally the future direction in which the quantum cryptography is headed forwards.

A theoretical model is under exploration towards the scope of developing a Quantum key distribution network. There is always a requirement of secured and confidential information processing so that the authentic and legitimate information one can get each time. Hence the quest for obtaining a perfect cypher continues. Considering the recent development in cryptography it was found that quantum mechanics exhibiting more solidarity when applied to cryptography and that generated a new dimension of secured information processing known as Quantum Cryptography. We propose a theoretical model of a network that will be used for quantum key distribution among  users of the network as the extension of two-party E91 protocol for multiple users simultaneously. Applying the concept of parallel Hadamard transform with optical fiber channels gives us the platform of WDM multiplexing and de-multiplexing through the network.
