A research paper on security of wireless network

Over the past few years, the IEEE 802.11 standard has been the focus of a large amount of research with respect to its security architecture and mechanisms. Our own research has shown a huge deficiency in the 802.11 standard with regard to security, as well as deficiencies in 802.11 network implementation and deployment. Furthermore, while several technologies have been (and continue to be) developed to either augment or replace the standard’s flawed portions, the difficulty of managing wireless networks has created a complex situation for network administrators even when they use the latest technologies. Like most advances, wireless LAN poses both opportunities and risks. The evolution of wireless network in few years has raised many serious security issues. In this Paper to fix security loopholes a public key authentication and key-establishment procedure has been proposed which fixes security loopholes in current standard. The public key cryptosystem is used to establish a session key securely between the client and Access point. A client -Agent based Rouge Access point detection system was developed to counter the threat of Rouge Access points in wireless LANs and are difficult to handle at the protocol level. Hence a centralized RAP was developed for organization where the area is quite large to cover manually or form a single location. An algorithm was also developed to detect Evil-Twin Access points, which cannot be detected by traditional methods. The algorithm works on fact that the evil-twin is placed at a distance from the good-twin to prevent direct detection.
