Wireless network connecting method, device and system

Abstract

The embodiment of the invention discloses a wireless network connecting method, device and system belonging to the network security field. According to the invention, a first access request is sent to a wireless access point; an authentication server sends a second access request; whether the wireless access point belongs to a trust wireless access point is authenticated, when the wireless access point belongs to the trust wireless access point, first identity authentication is carried out with a user terminal, a main secrete key is generated through negotiating with the user terminal; the main secrete key corresponding to a user name is sent to the wireless access point; an encrypted wireless network connection is built by negotiating with the user terminal according to the main secrete key; the problems that the data transmitted to the counterfeit public Wi-Fi by the user terminal and the data in the user terminal are in security threat are solved; only the trust wireless access point can obtain the secrete key corresponding to the user name; therefore, the encrypted wireless network connection is built by negotiating with the user terminal according to the main secrete key; the data security of the data transmitted by the user terminal and the data in the user terminal is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of network security, in particular to a wireless network connection method, device and system. Background technique [0002] With the widespread use of user terminals, wireless networks have become an important form for user terminals to access the Internet. A common wireless network is a Wi-Fi (Wireless-Fidelity, wireless fidelity) network. Most of the current commercial places provide public Wi-Fi for users to use for free. [0003] In the prior art, the ways for user terminals to access public Wi-Fi mainly include: no password access, verification code access and single password access. Among them: passwordless access means that after the user terminal obtains the SSID (ServiceSetIdentifier, Service Set Identifier) ​​of public Wi-Fi, it sends an access request to the wireless access point. Access to the public Wi-Fi; verification code access means that the user terminal needs to obtain the ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem that the data transmitted by the user terminal to the fake public Wi-Fi and the data inside the user terminal will be threatened by security after the user uses the existing access method to make the user terminal access the fake public Wi-Fi , the embodiment of the present invention provides a wireless network connection method, device and system
