Quantum cryptography

Abstract

We survey some results in quantum cryptography. After a brief introduction to classical cryptography, we provide the quantum-mechanical background needed to present some fundamental protocols from quantum cryptography. In particular, we review quantum key distribution via the BB84 protocol and its security proof, as well as the related quantum bit commitment protocol and its proof of insecurity.

Security in Computing Systems

“…Finally, we point to the recent development of quantum cryptography, surveyed, for example, by Bruss/et al [107], which will potentially require us to totally revise the traditional view of cryptography.…”

Introducing Quantum Cryptography Based Secured Encryption and Decryption Algorithms

“…The conventional cryptographic algorithms are based on mathematical problems such as discrete logarithm or integer factoring [7]. However, these problems are potentially not secure.…”

Framework for Wireless Network Security Using Quantum Cryptography

“…Quantum cryptography [7] is an evolving technology that provides safety and security for network communication by performing cryptographic tasks using quantum mechanical effects. Quantum Key Distribution (QKD) is a technique that is an application of quantum cryptography that has gained popularity recently since it overcomes the flaws of conventional cryptography.…”
