Fast Authentication Method for Wireless Local Area Network

WLAN (wireless local area network) connect the users and the network by using radio frequency signals.It reduces network cabling between the terminals and the network equipment.Thus WLAN has the following benefits: giving end users a great deal of mobility, convenience, saving network cabling project costs.WLAN can share the wireless traffic of 2G or 3G network.But WLAN authentication from the safety and convenience of comprehensive consideration has not been a fine solution.This paper analyzes the various existing problems of authentication used in the field of WLAN.A fast authentication method is proposed in this article considering the character of the terminal user.Compared with existing authentication methods, this method is fast, it improves the system applicability under the comprehensive consideration of accessibility and safety.This method is validated by experiments, so that users can easily access secure WLAN systems.
