Abstract

The invention relates to the field of data encryption, and discloses an encryption authentication method, device, equipment and storage medium. The method includes: receiving an authentication request sent by a device to be authenticated, and based on the authentication request, sending a public key authentication request to the device to be authenticated; receiving an authentication public key sent by the device to be authenticated; Perform verification processing to obtain a verification result; determine whether the verification result is a pass result; if so, obtain a preset character verification matrix frame, fill the character string into the character verification matrix frame, and obtain a character verification matrix ; According to the preset matrix decryption algorithm, decrypt the character check matrix to obtain a character decryption matrix; perform de-matrix processing on the character decryption matrix to obtain a decrypted string; determine whether the decrypted string belongs to the preset key string set; If it belongs, the device to be authenticated is determined as an authentication device; if not, the device to be authenticated is determined as a non-authenticated device.

Description

technical field [0001] The present invention relates to the field of data encryption, and in particular, to an encryption authentication method, device, device and storage medium. Background technique [0002] With the rapid development of portable devices and mobile network technology, 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 secure storage, so it is more important to design the system for secure 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 decryption key. [0003] In the highly competitive information age, a strong security measure is objectively needed to protect confidential data from being stolen or tampered with, so data encryption te...
