Abstract

The invention provides a data transmission method, device and system, equipment and a storage medium. The method comprises the steps of obtaining a key request sent by a terminal, wherein the key request comprises a data type of the user data; determining a symmetric key from a preset symmetric key mapping table according to the data type, wherein the symmetric key mapping table is a one-to-one mapping relation table of data types and symmetric keys; encrypting the symmetric key by using the terminal public key to obtain a first ciphertext; and sending the first ciphertext to the terminal, sothat the terminal decrypts the first ciphertext by using the terminal private key to obtain a symmetric key, and decrypts the encrypted data by using the symmetric key to obtain user data. According to the method, user data is stored outside the wearable device in a ciphertext mode, the symmetric key is stored on the wearable device, separate storage of the user data and the symmetric key is achieved, and the symmetric key is transmitted to the wearable device in a ciphertext mode.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission method, device, system, equipment and storage medium. Background technique [0002] Wearable devices, terminal devices and servers constitute a wearable device data network. Among them, wearable devices are used to detect the user's heart rate, measure the user's steps, check credit card points, sedentary reminders, and sleep detection. [0003] In the above wearable device data network, the wearable device obtains user data and transmits the user data to the terminal device, and the terminal device then transmits the data to the server, or the wearable device uploads the user data to the terminal device and the server respectively . The terminal device can also read user data stored on the server. Wherein, the data in the terminal device and the server are stored after being encrypted with the public key, but the key corresponding to the ...
