Abstract

The invention relates to a data encryption method, device and system, computer equipment and a storage medium. The data encryption method comprises the steps: establishing connection with a terminal to generate asymmetric keys, wherein the asymmetric keys are used for instructing the terminal to generate first symmetric keys; sending the public key of the asymmetric keys to the terminal, wherein the public key is used for instructing the terminal to encrypt the first symmetric keys through the public key so as to obtain second symmetric keys; and receiving the second symmetric keys transmittedby the terminal and decrypting the second symmetric keys through the private key of the asymmetric keys so as to obtain the first symmetric keys and encrypting the data to be transmitted through thesecond symmetric keys. According to the data encryption method, the data are encrypted by the hybrid encryption mode of asymmetric encryption and symmetric encryption so that the problem of key distribution in the symmetric encryption mode can be solved and fewer system resources are occupied.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a data encryption method, device, system, computer equipment and storage medium. Background technique [0002] With the development of network technology, the security of data during network transmission has also received more attention, and the security of data during network transmission can be protected by symmetric encryption. For example, when data is transmitted between the vehicle-mounted terminal and the monitoring platform, the data transmitted between the vehicle-mounted terminal and the monitoring platform can be encrypted. [0003] The traditional encryption method can generate a symmetric key by a machine, and then directly encrypt the data to be transmitted through the symmetric key. However, the security of the key in the symmetric key used in the traditional encryption method is low. Contents of the invention [0004] Based on this, it is ne...
