Data encoding and decoding method, device, equipment and storage medium

Abstract

The invention discloses a data encoding and decoding method, a device, equipment and a storage medium. The data encoding method comprises the following steps: firstly, preprocessing a plaintext to beencoded, secondly, generating a key according to pseudo-random parameters in the plaintext to be encoded, then, carrying out entropy encoding encryption, and finally, splicing user passwords to generate a formal ciphertext. The data decoding method comprises the following steps: decomposing a formal ciphertext into a user password segment and a pre-ciphertext segment, and firstly decoding the userpassword segment; secondly, obtaining a secret key, analyzing pseudo-random parameters, performing entropy decoding on the pre-ciphertext segments through the pseudo-random parameters to obtain a pre-plaintext, and finally restoring the pre-plaintext into a plaintext. According to the data encoding and decoding method provided by the invention, the security and the application range of the formalciphertext are improved, and the formal ciphertext has the compression capability while the security of the formal ciphertext is improved.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a data encoding and decoding method, device, equipment and storage medium. Background technique [0002] With the popularization of the mobile Internet and the large-scale application of the Internet of Things, e-commerce has entered thousands of households. Although e-commerce has provided convenience for the public, e-commerce still faces communication data security, personal privacy protection and Security issues such as payment security guarantees need to be resolved urgently. In particular, the current encryption and decryption technology still faces the problems of being easily cracked and not capable of compressing. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, and provide a data encoding and decoding method, device, equipment, and storage medium, which impr...
