Abstract
(EN)
The present disclosure relates to a data transmission method, a sending device for a data transmission system, a receiving device for a data transmission system, a data transmission system, and a computer-readable storage medium. The data transmission method comprises: updating encryption key information according to an interrupt signal; transmitting the updated encryption key information, and updating a key according to the updated encryption key information to obtain an encryption key; and where the number of first multiple frames of transmission data reaches a first pre-set number of frames, encrypting the data by means of the encryption key, and transmitting the data.
