Using Quantum Cryptography for Securing Wireless LAN Networks

摘要

Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. Key distribution is the problem of classical cryptography algorithm, and tends to provide safe channel to transport key. Quantum cryptography could distribute key in quantum channel. Eavesdropper can not access to key on quantum channel. If Eve attack on quantum channel QBER increases and she is detected. While the application of quantum cryptography in fiber network has significant advances, research on the application of quantum cryptography in mobile networks is still premature. In this paper, we analyze the interests of using quantum technique for the distribution of encryption keys in 802.11 wireless networks. We also propose a scheme for the combination of quantum cryptography and 802.11i security mechanisms for the establishment of the PTK (Pairwise Transient Key).
