Abstract

The invention relates to the field of data encryption, and discloses an encryption authentication method and device, equipment and a storage medium. The method comprises the following steps: receiving an authentication request sent by a to-be-authenticated device, and sending a public key authentication request to the to-be-authenticated device based on the authentication request; receiving an authentication public key sent by the to-be-authenticated device; performing verification processing on the character string according to a preset coordinate verification algorithm to obtain a verification result; judging whether the verification result is a pass result or not; if yes, obtaining a preset character check matrix framework, and filling the character string into the character check matrix framework to obtain a character check matrix; according to a preset matrix decryption algorithm, carrying out decryption processing on the character check matrix to obtain a character decryption matrix; carrying out matrix removal processing on the character decryption matrix to obtain a decryption character string; judging whether the decrypted character string belongs to a preset key character string set or not; if yes, determining the to-be-authenticated device as an authentication device; and if not, determining the to-be-authenticated device as a non-authenticated device.

Description

technical field [0001] The present invention relates to the field of data encryption, in particular to an encryption authentication method, device, equipment and storage medium. Background technique [0002] With the rapid development of portable devices and mobile network technologies, data security has been paid more and more attention. Data is the core part of the entire storage, and the encryption and protection of data is also the focus of safe storage, so it is more important to design the system for safe storage and encryption. Data encryption technology refers to converting a piece of information into meaningless ciphertext through an encryption key and an encryption function, and the receiver restores the ciphertext to plaintext through a decryption function and a decryption key. [0003] In the fiercely competitive information age, a strong security measure is objectively required to protect confidential data from being stolen or tampered with, so data encryption ...
