With the rapid growth in technology and increased use of internet in different sectors, more and more people now access Internet via Wireless Local Area Network (WLAN) due to easy installation, mobility, low cost etc. But easy usage of WLAN comes with many security flaws existed like weakness of RC4, which leads to security loopholes in WLAN. In this paper, we present several serious security flaws in wireless protocols, and discuss in detail each of the flaws, the underlying security principle violations, and implement relative attacks to show the weakness of WLAN protocols.
