Data transmission method, device and system, computer equipment and storage medium

Abstract

The invention relates to a data transmission method, device and system, computer equipment and a storage medium. The method comprises the following steps: performing bidirectional authentication with first interaction equipment; after the bidirectional authentication is completed, receiving encrypted interaction data obtained by encrypting interaction data based on a working key and sent by the first interaction equipment; the working key is obtained by mapping an authentication key adopted during bidirectional authentication by the first interaction equipment; according to a working key obtained by mapping the authentication key on the communication adapter, decrypting the encrypted interaction data; and through the simulated device node which can be identified by the second interaction device, transmitting the interaction data obtained by decryption to the second interaction device based on the native communication protocol of the second interaction device adaptive to the device node. By adopting the method, the universality of the software can be ensured while the secure transmission of the data is ensured.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a data transmission method, device, computer equipment and storage medium. Background technique [0002] In some specific application scenarios, there are two different devices for data transmission, and these two different devices can transmit data wirelessly. In the process of transmitting data wirelessly, in order to ensure data security The communication link is encrypted. However, in the process of data transmission, the use of communication link encryption may not be able to effectively ensure data security, and if the data encryption and decryption processes are performed on two different devices, it is necessary to perform software on the two different devices. Adaptation, such as Bluetooth software adaptation is required when using Bluetooth to transmit data, resulting in poor versatility of the software, so that the interaction between devices ...

However, in the process of data transmission, the use of communication link encryption may not be able to effectively ensure data security, and if the data encryption and decryption processes are performed on two different devices, it is necessary to perform software on the two different devices. Adaptation, such as Bluetooth software adaptation is required when transmitting data in Bluetooth mode, resulting in poor versatility of the software, so that it is impossible to ensure the safe transmission of data and the interaction effect between devices
