Embodiment 1

[0026] Such as figure 1 As shown, this embodiment includes the following steps:

[0027] Phase 1 of the activation process:

[0028] 1) The initial state of the smart device is Soft AP+STA coexistence mode, and the Soft AP interface broadcasts a beacon every 100ms.

[0029] 2) The bottom layer of the mobile terminal receives the information of nearby APs from the beacon, scans and filters out the SoftAP information of the smart device, and displays it in the device list.

[0030] 3) After the user selects a smart device to be connected in the list, the mobile terminal requests the server for the connection password of the smart device.

[0031] 4) The server judges that the smart device has no owner, and returns the password of the smart device; when the smart device has a legal owner, the server returns connection failure information to the mobile terminal.

[0032] 5) The mobile terminal connects to the Soft AP interface of the smart device according to the password respo...

Abstract

The invention relates to the technical field of wireless information safety and discloses a method for safely establishing the connection with a server and conducting authorization through a WIFI. The method is composed of an activation process needed by the initial connection and an authentication process needed by reconnection. According to the activation process, registering is conducted in the server through a mobile terminal, and an intelligent device and an AP are connected and are connected into the Internet. According to the authentication process, the mobile terminal conducts reactivation and reauthorization on the server through identification information, and achieves reconnection by obtaining a secret key of the intelligent device. According to the method, the BSSID and the WPA / WPA2 password of the intelligent device are bonded, the factory WPA / WPA2 password of the intelligent device is stored in the server, when the intelligent device is activated, the connecting secret key (the WPA / WPA2 password) needs to be obtained from the server, the one-to-one communication mode is adopted in the connecting process, the WPA / WPA2 safe access mode is supported, and the private data safety is ensured.

Description

technical field [0001] The present invention relates to a method in the technical field of wireless information security, in particular to a method for securely establishing a connection between an intelligent device and a server through WIFI and authorizing the use of a secure data communication method for a user. Background technique [0002] With the rise of the Internet of Things industry, smart home appliances have gradually entered people's lives. Connect home appliances to the network and activate them to cloud servers. Users can use mobile terminals to access cloud servers anywhere, and remotely query and control home smart devices. Then, how to establish the connection among smart devices, servers, and mobile terminals (users) has become a technical point worth considering at present. [0003] The current existing configuration method is: the mobile terminal connects to the wireless access point (AP), and sends a broadcast packet to the AP. The smart device captures...
