The Security of data and data communication is a top priority because the consequences of insecure data can have grave effects on both the economy and national security. Cryptography is used to secure the information transmitted over telecommunication lines through appropriate encryption techniques. Quantum Cryptography provides more security level then any classical cryptosystem as quantum computing works according to the laws of quantum physics and does not depend on hard mathematical functions. Hence, the resulting Quantum Cryptosystem is more secure and cannot be cracked easily. The quantum cryptography relies on two important elements of quantum mechanics-the Heisenberg uncertainty principle and the principle of photon polarization. The Heisenberg uncertainty principle states that, it is not possible to measure the quantum state of any system without distributing that system. The principle of photon polarization states that, an eavesdropper cannot copy unknown qubits i.e. unknown quantum states, due to quantum no-cloning Theorem. We are using a BB84 protocol for Quantum cryptography.This paper summarizes the current state of Quantum cryptography and exploration of quantum cryptography in Network Security.
