Method, device and system for authentication of WLAN (Wireless Local Area Network) access

Abstract

The embodiment of the invention provides a method, a device and a system for authentication of WLAN (Wireless Local Area Network) access and relates to the technical field of communication. By means of the method, the device and the system, the authentication of the WLAN access can be performed more conveniently and safely. The method comprises the following steps: receiving guest information transmitted by an authorization terminal by an authorization guaranteeing device, wherein the authorization terminal is a terminal for accessing the authorization guaranteeing device by adopting a guaranteeing person authorization certificate; transmitting an authorization request to an access authorization device, wherein the authorization request contains the guest information; receiving authorization response transmitted by the access authorization device, wherein the authorization response comprises a guest authorization certificate generated by the guest information; in addition, generating an authorization code, and transmitting the authorization code to the authorization terminal, wherein the authorization code comprises the guest authorization certificate and an address of the authorization guaranteeing device; then receiving the authorization request transmitted by the guest terminal, wherein the authorization request comprises the guest authorization certificate; forwarding the authorization request to the access authorization device. The embodiment of the invention is used for the authentication of the WLAN access.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication method, device and system for accessing WLAN. Background technique [0002] With the rapid development of wireless communication, the application of wireless local area network is becoming more and more extensive. Usually, when a user accesses a certain wireless local area network, the identity of the user needs to be authenticated. For example: For enterprises, when responding to the needs of guests to temporarily access the internal network of the enterprise, on the one hand: in order to control the population of the enterprise's internal wireless LAN, the enterprise needs to have a high security threshold for accessing the internal network of the enterprise; on the other hand, it needs to Guests can easily access the internal network of the enterprise. [0003] In the access authentication method in the prior art, the guest can perform access ...

Problems solved by technology

[0003] In the access authentication method in the prior art, the guest can perform access authentication through mobile phone verification code authentication / third-party application program authentication (such as QQ number authentication, Weibo number authentication, and WeChat number authentication, etc.), and access to the enterprise Although this method can allow guests to easily access the internal network of the enterprise, the security access threshold is too low, so that the enterprise cannot effectively control the access population
