Secure communications is a vital need of the world, and basic features quantum mechanics seemingly offer fundamental new tools for achieving this security. But do these really work? This review gives due attention to real-world problems with experimental cryptography, but heart an in-depth survey analyses developed prove security techniques introduced by Wiesner, Ekert, Bennett, Brassard. A bro...

Ever since its inception, cryptography has been caught in a vicious circle: Cryptographers keep inventing methods to hide information, and cryptanalysts break them, prompting cryptographers invent even more sophisticated encryption schemes, so on. But could it be that quantum information technology breaks this circle? At first sight, looks as if just lifts the competition between next level. In...

Quantum cryptography is an emerging technology in which two parties can secure network Communications by applying the phenomena of quantum physics. The security of these transmissions is based on the inviolability of the laws of quantum mechanics. Quantum cryptography was born in the early seventies when Steven wiesner wrote “conjugate coding”. The quantum cryptography relies on two important e...

Information protection has been an important part of human life from ancient time. In computer society, information security becomes more and more important for humanity and new technologies are emerging in an endless stream. Cryptography or cryptology is a technology to convert the information from readable state into nonsense, or do the contrary transformation. Information transmission and st...

Optical burst switching (OBS) is the most promising optical switching technology for the future Internet, but it suffers from security vulnerabilities. In this paper, we propose to embed a security framework which incorporates the strengths of classical and the emerging quantum cryptography techniques in the native OBS network architecture, providing a means to make the future Internet secure f...
