Quantum cryptography - A modern approach

Abstract

In Our daily life we are getting very much dependent on Internet or Virtual Reality. They are nothing but an illusion of a Cyberspace. It has effect on our every aspect of life, like Education, Sports, and Health etc. We are using the term Cryptography which is the science of using mathematics to encrypt and decrypt data. We had used various Encryption standards in back days namely, DES, AES, RSA, Elliptical AES etc. But nowadays we are using Quantum Cryptography for this. It is nothing but use of Physics (mainly Quantum Physics) for Encrypting the data. In this Research paper we will mainly focus on the new approaches that come in the path of Quantum Cryptography. We will also view some interaction of Quantum Cryptography in future Internet services. Quantum computing is yet to be explored but still the explored part has the capabilities to counter the “alien” hacking protocols if tested over any System. Older System were using protocols like RSA, AES, DES even some of them are more capable than our need, but the use of QC will not only secure the systems but there are major chances that eavesdropper got caught while eavesdropping. Also QC is a pathway to secure communication. This paper includes the review of older state of Quantum Cryptography which will give us information about QKD algorithms and its protocol and we will also overview on its risk and security features. We will also provide a glimpse of current various works going in various Educational Institutions.
