Abstract

The invention discloses a data transmission method and device, a computer device and a storage medium, and the method comprises the steps: enabling a server to obtain a preset encryption field table when a to-be-transmitted task is detected to exist; the server determining a dynamic encryption field and an encryption algorithm corresponding to the current moment according to the encryption field table; the server encrypting data corresponding to the to-be-transmitted task based on the dynamic encryption field and an encryption algorithm to generate to-be-transmitted ciphertext data; and the server sending the ciphertext data to be transmitted to the client corresponding to the task to be transmitted; the client receiving ciphertext data to be transmitted; the client determining historicaltime information corresponding to the ciphertext data to be transmitted; the client acquiring a corresponding dynamic encryption field and a decryption algorithm based on the historical time information and a preset encryption field table; and the client decrypting the to-be-transmitted key data based on the dynamic encryption field and a decryption algorithm to generate plaintext data. Therefore,by adopting the embodiment of the invention, the risk of data leakage can be reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data transmission method, device, computer equipment and storage medium. Background technique [0002] Due to the rise of the communication age and society, data applications have been updated alternately with the development of the Internet. Furthermore, in the process of data transmission between the server and the client, it is usually necessary to perform an encryption operation on the transmitted data, so as to ensure the security of the data. [0003] In traditional data transmission, the sender can use the pre-agreed character string as an encryption field to encrypt the data and then transmit the data to the receiver. After receiving the data, the receiver also uses the pre-agreed character string The string is used as the decryption field to decrypt the data. If criminals have enough time, or have extremely powerful hardware devices, they can decipher the i...
