The main challenge in the current era is how to secure the communication networks on which the information is transmitted from source to destination. Different techniques and algorithms are used for securing the communication system and providing a more secure system that ensures confidentiality and the integrity of data. The secret in this system includes the shared key algorithm and the public key. By using the Quantum Cryptography technique, a more secure communication network is achieved. This technique of Quantum Cryptography is based on the following two elements, photon polarization and the principle of uncertainty. Photon polarization ensures that an eavesdropper cannot copy or even try to read the information which is being transmitted by using photons. The principle of uncertainty states that it is impossible to measure or observe the state of photons without disturbing their actual state. The main focus of this paper is on photon Cryptography and how this can be used to make the network more secured. Finally, we discuss the future of Quantum Cryptography. [ABSTRACT FROM AUTHOR]
