Traditional Cryptography versus Quantum Cryptography

Abstract

Cryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). Traditional cryptography created security protocols by intersecting the principles of mathematics, computer science and electronics. An adversary or a cryptanalyst with his determination and the computational power of a soon-to-be available quantum computer can break the security using his resources. This gave rise to the introduction of an entirely new field of cryptology called Quantum Cryptography which makes use of the quantum mechanical effects to make or break the cipher. This paper highlights the need of Quantum Cryptography and also elaborates the basic concept behind it
