High performance quantum cryptography architectures in IEEE 802.11 WLAN

Quantum Key Distribution (QKD) is an ingenious application of quantum mechanics in information field. Wireless Local Area Network (WLAN) is gaining popularity as they are fast, cost effective, flexible and easy to use. They are, however, faced with some serious security challenges and the choice of security protocol is a critical issue for IT. In this paper, it analyzes the IEEE 802.11i wireless networking amendment with respect to data confidentiality, integrity, mutual authentication and availability. It provides novel high-performance quantum cryptography architectures in IEEE 802.11 WLAN by establishing a quantum key over a long distance. The supplicant sends qubits to the authenticator server by sharing EPR. Compared with the classical network architecture, it is proved in theory that an eavesdropper (Eve) invariably introduces errors within communication network if it wants to gain useful information. Quantum cryptography guarantees the security of the network.
