Quantum cryptography and security analysis

Abstract

Cyberspace has become one of the most preferred and popular carrier of information exchange these days. A substantial amount of research especially on quantum computers and security issues has been continuously going on. In this paper, our focus is on quantum cryptography. An in-depth security analysis of quantum key distribution (QKD has been provided here. Our approach not only promises long-term security to digital data but also simplifies data encryption method through QKD.
