Implementation of BB84 Protocol on 802.11i

Quantum key distribution is a new method in key distribution system in cryptography used to transmit secret key between two legitimate parties. This method is an invention in quantum cryptography as part of quantum mechanics which solves the key distribution´s problem in cryptosystem by providing a secure communication channel between two parties with absolute security guaranteed by the laws of physics. Communication not only occurred in wired medium but also in wireless medium. WLAN as a wireless medium are much noisier and less reliable in general than wired mediums. This type of noise will generate different numbers of key length and also different level of error rate estimation. Thus, how much secure of the data could be protected on wireless communication? In this study, we implement BB84 protocol on 802.11i wireless local area network (WLAN) to show the affect of noise and eavesdropper could make the data transmission is much secure in wireless medium. In our study shows that implementation of BB84 in 802.11i is able to secure the key distribution from being stealing by the third party.
