摘要：Various approaches and techniques are being constantly studied to ensure a secure communication. Modern cryptographictechniques face a serious threat by the progress of computing power. They generally make use of large numbers which can be factorized.The use of this make the communication vulnerable to attacks as it is now possible to reverse the one-way functions. Motivated by thisconcern, Quantum Cryptography was introduced to provide secure communication. It depends on two important aspects of quantummechanics, the Heisenberg Uncertainty principle and the principle of photon polarization. This paper focuses on the principle and workingof Quantum Cryptography and compares various Quantum Key Distribution Protocols such as BB84 and B92. It also introduces othercryptographic techniques which are popularly used
