Abstract
An attack prevention method includes: receiving an authentication request frame; and in response to receiving the authentication request frame, replying with an authentication response frame that is sent to a non-access-point (non-AP) station (STA), wherein the authentication request frame includes a timeout interval element that carries Authentication Comeback time. Another attack prevention method includes: ignoring each specific request frame that is received within a period in which a connected non-AP STA operates under a power saving mode, wherein each specific request frame includes one of an authentication request frame, an association request frame, and a reassociation request frame.
