Wireless Security Protocols (WIFI) Project in Wireless Network 2011

The use of security protocols to protect a high growth segment of wireless computer networks is not as safe from attackers as perceived. Only recently have wireless local area networks (WLANs) evolved to a mission critical stage. They are a vital part of information technology infrastructures in business, academe, government, and home usage. With this new emphasis around the reliance of WLANs, a problem of data security is front and center for exploitation by intruders. The amount of research in implementation and theoretical application is generating many questions relating to vendors’ claims of security over wireless connectivity.Today, several security protocols are in practice, but yield little if any protection against attackers. The use of the link-layer security protocol, wired equivalent privacy (WEP) as a function to encrypt wireless network transmissions is thought to be impenetrable. Many researches have created theoretical and practical attack routines to show these functions and protocols are not as secure as previously believed. An IEEE working group has released several standards for the wireless fidelity (Wi-Fi) 802.11 security protocols used in WLANs. Many Research groups recommend using virtual private networking (VPN) protocols over Wi-Fi as a means of increased security due to Wi-Fi’s shortcomings. Others see cryptography as the only answer to a secured WLAN and others propose combinations of key management techniques and elliptical curve routines for encryption as a solution to this insecurity.
