Data encryption method, device, computer device and storage medium

Abstract

The invention relates to a data encryption method, a device, a computer device and a storage medium. The method comprises the following steps: acquiring a request data packet; extracting business dataand a request type in the request data packet; acquiring a private key based on the request type; acquiring a private key based on the request type; processing the business data with the private keyto obtain a processing result; performing a format conversion on the processing result to obtain a message in a unified format; sending the message with unified format to a terminal. According to thedata encryption method, the device, the computer device and the storage medium, the service data is encrypted by using the private key according to different request types and different scenes, and different request types have different encryption types, thereby improving data security after encryption. The encryption is performed in the storage device, so that the service data to be encrypted cannot escape the storage device once it is written which ensures that the data cannot be tampered and copied, and the convenience of the private key is ensured. Setting different private keys in different scenes can effectively control the problem of malicious use of the private key, and dynamically determining the scene corresponding to the request type can eliminate the cumbersome memory.

Description

technical field [0001] The present invention relates to a data encryption method, and more specifically refers to a data encryption method, device, computer equipment and storage medium. Background technique [0002] Cryptography is a technique used to obfuscate, in the hopes of turning normal, recognizable information into something unrecognizable. Of course, for a small number of people, this unidentifiable information can be reprocessed and recovered. [0003] Existing cryptographic privacy information, that is, encrypted data is generally encrypted and decrypted by the private key, and the current private key is generally hosted in the management mode of the server, which has security risks and is easy to be tampered with or copied. If the user keeps the secret key by himself Inconvenient and easy to lose, if the secret key is stored in the UKEY wallet, since the UKEY wallet only provides a storage function, the information can still be stolen after storing it.

AI Technical Summary

Problems solved by technology

[0003] Existing cryptographic privacy information, that is, encrypted data is generally encrypted and decrypted by the private key, and the current private key is generally hosted in the management mode of the server, which has security risks and is easy to be tampered with or copied. If the user keeps the secret key by himself Inconvenient and easy to lose, if the secret key is stored in the UKEY wallet, since the UKEY wallet only provides a storage function, the information can still be stolen after storing it

[0004] The above three methods all have the risk of the private key being stolen, which leads to the risk that the encrypted data can still be tampered with and copied, and the security is low
