Abstract

The invention discloses a data transmission method and device, computer equipment and a storage medium, and the method comprises the steps: determining an optimal encryption algorithm and a dynamic encryption key at a current moment according to a preset encryption algorithm table when a server detects that to-be-transmitted data exists; performing word segmentation processing on the to-be-transmitted data to generate a plurality of word groups corresponding to the to-be-transmitted data; generating a Huffman dictionary of the to-be-transmitted data based on the plurality of word groups corresponding to the to-be-transmitted data; compressing and encoding the to-be-transmitted data according to the Huffman dictionary to generate encoding information of the to-be-transmitted data; encrypting the Huffman dictionary of the to-be-transmitted data according to the optimal encryption algorithm and the dynamic encryption key at the current moment to generate an encrypted Huffman dictionary; and sending the coded information of the to-be-transmitted data, the encrypted Huffman dictionary and the dynamic encryption key at the current moment to the client. Therefore, by adopting the embodiment of the invention, the network broadband required to be consumed during data transmission 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] Encrypted data transmission is an important technology in the field of data security. With the advent of the era of big data, data security issues have attracted more and more attention, especially in the financial field, such as: sensitive information of customers, access to financial information systems , transaction quantification, encryption of sensitive information, etc. The leakage of sensitive information will not only cause losses to the operation of the enterprise, but more importantly, affect the reputation of the enterprise. Therefore, in the modern Internet industry, especially the financial and insurance industry, it is very important to encrypt and transmit sensitive data well. [0003] At present, encryption of sensitive data and fast transmission are...
