Key Agreement & Authentication Protocol for IEEE 802.11
WPA and WPA2 (Wi-Fi Protected Access) is a certification program developed by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Wi-Fi alliance to secure wireless networks. The alliance defined the protocol in response to several weaknesses researchers had found in the previous Wired Equivalent Privacy (WEP) system. Many sophisticated authentication and encryption techniques have been embedded into WPA but it is still facing a lot of challenging situations. In this paper, the authors discuss the vulnerability & weakness of WPA.
