Abstract

Broadly, Cryptography refers to the passing of secret information from one place to another securely so that only intended receivers can decrypt it. Security of the modern public key cryptographic algorithms and protocols is mainly dependent on the complexity of the factorization of the product of large prime numbers. But due to technological developments in the field of computation and evolution of new mathematical techniques, the problem of the factorization of the product of integers is not complex anymore nowadays. The growing research interests in Quantum computing technology is also making the modern public cryptographic algorithms unsafe. Researchers have proved that modern cryptographic algorithms such as RSA are breakable using quantum computers in polynomial time complexity. Therefore, attempts are being made to design new cryptographic algorithms using Quantum Computing techniques. Quantum cryptography is an emerging field which works on principles of quantum physics. In this paper, an attempt has been made to introduce quantum cryptography, analysis on supremacy of quantum cryptography over modern cryptography, discussion on key distribution using quantum physics, and implementation challenges in quantum key distribution. We ...
