Wireless network connection method, device and system

Abstract

The invention discloses a wireless network connection method, device and system, belonging to the field of network security. The method comprises the following steps: a user terminal sends an access request to a wireless access point; the wireless access point sends a key query request to an authentication server; the authentication server sends a corresponding key query result to the wireless access point when the wireless access point belongs to a trusted wireless access point; the wireless access point acquires a corresponding authentication key; the user terminal generates an authentication key corresponding to the own MAC address; and the wireless access point and the user terminal negotiate to establish an encrypted wireless network connection according to the separately-owned authentication keys. According to the wireless network connection method, device and system disclosed by the invention, the problem that both the data transmitted to the fake public Wi-Fi by the user terminal and the internal data of the user terminal are subject to security threats can be solved; and only the trusted wireless access point can acquire the authentication key to establish the encrypted wireless network connection with the user terminal, and the effect of improving the security of the data transmitted by the user terminal and the internal data of the user terminal can be achieved.

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. User terminals refer to terminals that can search and connect to Wi-Fi networks . Among them: passwordless access means that the user terminal sends an access request to the wireless access point after obtaining the SSID (Service SetIdentifier) ​​of the public Wi-Fi, and the wireless access point directly al...
