Securing Encryption Key Distribution in WLAN via QKD

Society becomes more and more electronic and many daily applications, like those of e-commerce, need a height level of security because of the sensitivity of the manipulated data. Cryptography is the main way to ensure security of data, such passwords, cards numbers, etc. However, the classical cryptography suffers from relevant problematic of secured key sharing. According to Shannon theory, a secured encryption key is the one generated randomly and used only once time. The Quantum Key Distribution, based on quantum physic lows, offers the opportunity to generate such a key. It seems also, to be the only technique that does not present vulnerability against the quantum calculating power. In this paper, we present an enhanced scheme for deriving a secured encryption key for WLAN using the quantum key distribution principals.
