Data transmission method and device

Abstract

The data transmission method provided by the invention comprises the following steps: when service data sent by a client is received, determining whether a data interface for receiving the service data is provided with a first security switch or not; when the data interface is provided with the first safety switch, judging whether the data state of the service data is matched with the current on-off state of the first safety switch or not; wherein the on-off state of the first safety switch is used for representing whether to decrypt the client data received by the data interface; if the datastate of the service data is not matched with the current on-off state of the first safety switch, sending state updating information to the client to trigger the client to update a created safety sign according to the state updating information. By arranging the first safety switch, whether encryption and decryption need to be conducted in the data transmission process or not can be effectively controlled, an operation load of the server can be effectively reduced, and data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of network security, in particular to a data transmission method and device. Background technique [0002] With the popularization of Internet applications, people exchange data through servers and clients in the Internet to obtain the required data. Correspondingly, the server and the client are provided with multiple different types of data interfaces for transmitting different types of data. In order to ensure the security of data during transmission, an encryption and decryption algorithm can be set at the corresponding interface. For example, when the client transmits data through the data interface, the client encrypts the data through an encryption algorithm and sends it to the server. After receiving the encrypted data sent by the client, the corresponding interface of the server decrypts it through a corresponding decryption algorithm to obtain the data. [0003] The inventor researched the data transmissio...

AI Technical Summary

Problems solved by technology

[0003] The inventor conducted research on the data transmission process between the existing server and the client and found that in the process of data transmission through the interface, once the encryption and decryption algorithm is set at the interface, the encryption and decryption process cannot be changed. In some special cases For example, when the server is running under a heavy load, some data that does not need to be encrypted and decrypted still needs to be encrypted and decrypted, which increases the running load of the server and affects the efficiency of data transmission.
