Embodiment Construction

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0017] figure 1 It is a schematic flow diagram of the data transmission method provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the method includes:

[0018] 101. The terminal determines the security level of the WiFi device according to the identifier of the currently connected WiFi device.

[0019] In practical applications, the security level of each WiFi device needs to be established in advance. Specifically, the security levels of the WiFi devices may be divided according to actual application conditions. For example, the WiFi device manually added by the user is a commonly used WiFi connection device trusted by the us...

Abstract

The invention provides a data transmission method and a terminal. The data transmission method includes the steps that the terminal determines the safety level of WiFi equipment according to identification of the wireless fidelity WiFi equipment connected currently; according to preset encryption mechanisms corresponding to all safety levels, the terminal adopts the encryption mechanism corresponding to the safety level of the WiFi equipment to encrypt first data to be transmitted; the terminal transmits the first encrypted data and the safety level of the WiFi equipment to an encryption and decryption server through the WiFi equipment. By means of the method and the terminal, while data safety can be ensured, consumption of processing resources and delay of data transmission due to unnecessary encryption are reduced, and therefore the efficiency of data transmission is effectively improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and a terminal. Background technique [0002] With the popularization of wireless fidelity (WIreless-Fidelity, WiFi for short) devices, more and more public places will provide users with free WiFi device connections to facilitate users to surf the Internet. Based on this, some criminals have also begun to set up phishing WiFi in some public places. When users connect to these unsafe WiFi devices to surf the Internet, their financial information and private data are often illegally intercepted, resulting in a decrease in the security of user data transmission. [0003] In this regard, an existing data transmission scheme is to uniformly adopt a preset encryption mechanism for data transmitted through a WiFi device, encrypt the data, and send the encrypted data to a corresponding server. Based on the above scheme, the transmission security of user data...
