Access authentication method of wireless local area network, server and authentication system

Abstract

The invention discloses an access authentication method of a wireless local area network. The method comprises the steps that: a server receives access information sent by first user equipment, and the access information carries the identity information of the first user equipment; the server sends an access request to the second user equipment according to the access information; if the server receives a confirmation instruction sent by the second user equipment for the access request, the server generates a challenge code and generates a first access password according to the challenge code; the server sends the challenge code to the first user equipment such that the first user equipment generates a second access password according to the challenge code; and the server completes EAP certification through the first access password and the first user equipment. Correspondingly, the invention discloses the server and an authentication system. By using the access authentication method, the server and the authentication system, a problem of dictionary attack can be solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless local area network access authentication method, server and authentication system. Background technique [0002] WIFI technology is a technology that can connect terminals such as personal computers and handheld devices to each other in a wireless manner. With the rapid development of network technology, WIFI technology has penetrated into every aspect of life. On the other hand, with the rapid increase and popularization of portable communication devices, more and more user devices will perform WIFI access. All of these put forward higher requirements for the security of wireless communication. [0003] At present, when a portable device (including a device with a card and a device without a card) performs WIFI access, it usually uses a user name and a password as input information to perform identity authentication. Although this method is easy to u...
