This is because whether you use a computer or a mobile phone, as long as you access the Internet via WiFi, data may be Intercepted by a hacker computer that controls the WiFi device, including username and password information that was not encrypted. The hackers just like to set up their own WiFi hotspots with confusing names like CMCC1 and KFC2. They don't have passwords. If the mobile phone and other terminals open the WiFi automatic search, it is easy to connect to the hacker's hotspot. Moreover, according to hackers, in places where free WiFi is available, such as Starbucks and McDonald's, you can steal personal information and passwords from mobile Internet users in 15 minutes. It can be seen that the security of WiFi connections in public places is particularly important. At present, for most users, it is often necessary to connect to the network when they need to use it, but forget to disconnect when not in use, which greatly increases the security risk.

Moreover, with the rapid development of Quick Response (QR) (a type of two-dimensional barcode), the application range of QR codes is more and more extensive. For example, the related art can save the AP name, password, and the like in the form of a QR code, so that the user can obtain the corresponding information, thereby quickly joining the network, and avoiding obtaining the access point type, password, and the like directly through the viewing. To improve the confidentiality of information. However, this fast connection scheme based on QR code technology has security flaws, that is, the user can quickly connect to the network by scanning the two-dimensional code without knowing the network security of the connected WIFI. Increased the security risk of the terminal.

In view of the problem that the user in the related art cannot determine the security of the WIFI network, the terminal has an unavoidable security risk when connecting to the WIFI by itself, and no effective solution has been proposed yet.

Step S705: The WiFi security protection client determines whether there is a high priority record in the locally saved WiFi network information (SSID). If yes, step S716 is performed; if no, step S719 is performed.

Step S706, the WiFi security protection client opens the WiFi switch of the mobile terminal and attempts to log in to the high priority WiFi network hotspot. If the login is successful, step S717 is performed; if the login fails, step S718 is performed;

Step S707, the WiFi security protection client reminds the user of the currently registered hotspot SSID name, and then proceeds to step S715;

Step S708, the WiFi security protection client asks the user whether to agree to try to log in to other trusted WiFi network hotspots. If yes, step S719 is performed; if not, step S716 is performed.

Step S709, the WiFi security protection client initiates a network search and determines whether it is in the trusted SSID list saved by the client according to the searched WiFi network information (SSID). If yes, go to step S710; if no, go to step S711.

Step S710, the WiFi security protection client determines to read the corresponding login user name and password and initiates connection and login. If the login is successful, step S707; otherwise, step S711 is performed.

In step S711, the WiFi security protection client prompts the user that there is no secure network.

Step S715, the WiFi security protection client determines whether the terminal successfully synchronizes the network time. If the time synchronization is successful, step S716 is performed; if the time synchronization fails, step S717 is performed.

Step S716, the WiFi security protection client calculates and compares the duration T1 of the key expiration update time (the key expiration update time - the system time after synchronization) and the duration T2 of the single access time limit, and takes the timer of the minimum value. As a standard time threshold for the security reminder, then step S718 is performed.

In step S717, the WiFi security protection client calculates and compares the duration T2 of the single-time access time limit and the reciprocal zero-length duration T3 of the synchronization counter, and takes the timer of the minimum value as the standard time threshold of the security reminder, and then performs step S718.

Step S718: After the timer expires, processing according to the preset network security policy: if the network is automatically forcibly disconnected or the user is prompted to continue using the network, the QR code needs to be re-acquired.
