A Security Policy of WLAN Data Transmission Based on Logistic Chaotic Modulation

Abstract

Analyzing on WEP (Wired Equivalent Privacy) indicates many defects existing in security. A security policy of WLAN data transmission based on logistic chaotic modulation is presented. The improved Logistic mapping can carry information in the WLAN data frame through the change of single parameter μ, which can lead to morphological changes of chaotic attractors. The receiver decision device is used to restore the original signals at the recieving end. The results of simulation show that the proposed policy can secure the data transmission effectively. In addition, throughput, time delay and other properties meet customers' needs basically. And the effectiveness and availability of this policy are also proved.
