A Study on Intensified scheme to WLAN Secure based on IEEE 802.1x Framework

The IEEE 802.1x can be using various user authentication mechanisms: One-Time Password, Certificate-Based TLS, Challenge/Response and Keberos through EAP(Extended Authentication Protocol). But, IEEE 802.1x also has vulnerabilities about the DoS, the session hijacking and the Man in the Middle attack due to the absence of AP authentication. In this paper, we propose a WLAN secure system which can offer a safety secure communication and a user authentications by intensified the vulnerability of spoofing and DoS attacks. The suppose system offers a safe secure communication because it offers sending message of integrity service and also it prevents DoS attack at authentication initial phase.
