Document Type and Number:
WIPO Patent Application WO/2023/174038
Kind Code:
A9
Abstract:
Provided in the present application are a data transmission method and a related device. An execution process of the method comprises: receiving a transmission preparation request which is sent by a user end before sending transmission data, and generating configuration information according to at least some data in the transmission preparation request; generating an authentication request on the basis of the configuration information and by means of a trusted execution environment, and sending the authentication request to the user end, such that the user end performs envelope encryption on the transmission data according to the authentication request; receiving feedback information which is sent by the user end, wherein the feedback information comprises transmission data which has been subjected to envelope encryption; and decrypting the feedback information to obtain the transmission data. Transmission data is encrypted during a data transmission process by means of envelope encryption, such that the encryption method is easy and quick to operate, the security of the transmission data can be also effectively improved, and the data transmission process can be completed by means of only one round of interaction, thereby effectively improving the data transmission efficiency.
