Weakness analysis and attack test for WLAN

As the rapid development of Internet and information technology, more and more people now access Internet via Wireless Local Area Network (WLAN) with many features such as: mobility, convenience and low-cost, but the security flaws existed in RC4, WEP and WPA lead to security issues in WLAN. In this paper, we present several serious security flaws in these protocols, stemming from misapplication of cryptographic primitives and discuss in detail each of the flaws, the underlying security principle violations, and implement relative attacks to show the weakness of WLAN protocols.
