Abstract
Wireless communication can provide ubiquitous access to the Internet and more convenience than wired communication. Due to the wide open nature of wireless radio, security over a wireless environment is more complicated. From the initial IEEE 802.11 to IEEE 802.11i, more robust security methods have been adopted to eliminate underlying attacks. IEEE 802.11i is based on the assumption that all participants are honest that they will act as they are expected. But usually it is not true. How to recognize a genuine user, how to keep authentication data safely, and how to prevent dishonest supplicant accessing WLAN are big challenges. Trusted Computing can be used to improve security status of endpoint. Applying Trusted Computing technology can solve these challenges and enhance WLAN security.
