Abstract

The invention provides a data encryption method, a data decryption method, a user side, a server and a data management system. When applied to the user side, the data encryption method comprises the following steps: receiving a plaintext data key and a ciphertext data key generated by a key management server from the key management server; encrypting a to-be-encrypted file by utilizing the plaintext data key to generate a ciphertext file; storing the ciphertext data key and the ciphertext file. The data decryption method comprises the following steps: obtaining a ciphertext data key stored ina user side; sending the ciphertext data key to a key management server; receiving a plaintext key generated by the key management server according to the ciphertext data key from the key management server; and decrypting the key file to be decrypted according to the plaintext key. Data encryption and secret key management are considered, developers do not need to encrypt and decrypt secret keys,and safety and reliability of data are truly achieved.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to the technical field of data encryption and decryption, specifically a data encryption and decryption method, a client, a server and a data management system. Background technique [0002] In the era of big data, the value of data is beyond doubt, and the data security it brings has increasingly attracted the attention of enterprises. Since daily executives, especially developers, do not have sufficient awareness of data security, data is persisted in clear text, which is easy to be stolen by some internal personnel for other purposes. Even security-conscious personnel would simply encrypt the data, but the key is casually stored elsewhere. However, many enterprises have very strong security awareness and have high requirements for data encryption, especially when it comes to sensitive data such as amount, employee information, and enterprise information. In this w...
