Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] For ease of understanding, some technical concepts involved in the embodiments of the present invention are firstly introduced.

[0057] public key and private key

[0058] The public key refers to the public key, which does not need to be kept secret, and the decrypting party can obtain it through various channels; while the private key refers to the key held only by the encrypting party itself, which needs to be kept secret. A public key corresponds to a private key; the public key and the private key together form an asymmetric encryption method. Asymmetric encryption means that the information encrypted with the public key can only be decrypted with the corresponding private key, and the information encrypted with the priva...

Abstract

The embodiment of the invention discloses a wireless network connection method, device and system, belonging to the field of network security. The present invention sends the first access request to the wireless access point; sends the second access request to the authentication server; verifies whether the wireless access point belongs to the trusted wireless access point, and communicates with the user terminal when it belongs to the trusted wireless access point Perform the first identity authentication, negotiate with the user terminal to generate a master key; send the master key corresponding to the user name to the wireless access point; negotiate with the user terminal to establish an encrypted wireless network connection according to the master key; The data transmitted by the public Wi-Fi and the data inside the user terminal will be threatened by security; only the trusted wireless access point can obtain the master key corresponding to the user name, so as to communicate with the user terminal according to their respective Some master key negotiations establish an encrypted wireless network connection, which improves the security effect of the data transmitted by the user terminal and the internal data of the user terminal.

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 the user terminal sends an access request to the wireless access point after obtaining the SSID (Service Set Identifier) ​​of the public Wi-Fi, and the wireless access point directly allows the user to The terminal accesses the public Wi-Fi; the verification code ac...
