Quantum Cryptography: The Future of Secure Data Communication

Authors

Abstract

This paper deals with an introduction to quantum cryptography, differences between conventional and quantum cryptography, its applications, drawbacks & its advantages over conventional cryptography. Quantum cryptography is the phenomenon of making cryptographic tasks using the principles of quantum physics. Quantum key distribution (QKD) is one of the leading applications of quantum cryptography which makes the applications, servers, databases, emails & social media handles more securable, i.e., not hackable. Quantum cryptography is a trail to permit two users of a common communication channel to transmit or create secure information between them. This information which is in the form of a random string of bits can be converted to even more strong and unbreakable if used with the help of quantum cryptography. The advantage of quantum cryptography over conventional cryptography is that the information which is being stored or shared is in the quantum state which means it is highly impossible to hack or copy the data. The Heisenberg uncertainty principle and quantum entanglement can be exploited as a system of secure communication in this process. Quantum cryptography takes advantage of quantum’s multiple states, including its “no change theory,” which implies it cannot be unwittingly interrupted. The Uncertainty principle states that it is impossible to simultaneously know the accurate position and momentum of a particle. Quantum cryptography holds both guarantees and threats for our current crypto logical infrastructure. The pretty obvious threat is that quantum computers might decrypt data that has already been encrypted using many of our current systems. However, it conjointly holds the promise of secure communications channels for key distribution. Sooner or later, with correct & clean usage of quantum technology, it may even be possible to build entire encryption systems that are considered unbreakable and unbackable.
