Abstract: The paper introduces the basic concept of WLAN, and on the base of analyzing the theory of security policy, discusses the security problem of WLAN. A design of security system that is based on embedded flat is proposed, which combines encryption algorithm with higher security and advance verification policy. It is of some value in solving the security problem in WLAN.
