So WEP and WPA are proposed to improve the security of WLAN as two popular standards. But they are not perfect. In this article we analyze their shortcomings and raise two mechanisms named d-WEP and d-WPA-PSK. The d-WEP adopts the frequency of ARP requests...
As the critical security flaw of WEP is discovered, concern of researchers is more and more attracted by the scheme of WPA/WPA2 which includes 802.1X, authentication protocol, and TKIP and CCMP encryption algorithms. In this paper, an overview of WPA/WPA2 is supplied. And then, the vulnerabilities of WPA/WPA2 and current researches in the method of attacking WPA/WPA2 are introduced. In the last part,...
