Embodiment Construction

[0082] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0083] With the continuous development of Internet technology, a large amount of data is also generated. In order to avoid data leakage, the method of encrypting data can usually be used to ensure data security.

[0084] Currently, when encrypting data, encryption and decryption algorithms can be divided into symmetric encryption algorithms and asymmetric encryption algorithms accord...

Abstract

The invention is suitable for the technical field of computers, provides a data decryption method, data processing equipment and encryption equipment, and is used for solving the defects that in the prior art, software encryption is not high in security, and it is difficult for hardware encryption to adapt to a high-concurrency scene, and the method comprises the following steps: obtaining a decryption request for first encrypted data; determining a first key identifier according to the decryption request; determining a first key and a second key identifier corresponding to the first key identifier; sending the first key and the second key identifier to the encryption equipment, and receiving a second key obtained by the encryption equipment by decrypting the first key by using a decryption key corresponding to the second key identifier; and decrypting the first encrypted data by using the second key to obtain first data.

Description

technical field [0001] The application belongs to the field of computer technology, and in particular relates to a method for decrypting data, a data processing device and an encryption machine. Background technique [0002] More and more informatization involves encryption and protection of data, which requires encryption and decryption functions. Existing encryption technologies mainly include software encryption and hardware encryption. [0003] Symmetric key encryption algorithms are currently the most widely used software encryption methods, and commonly used algorithms include AES, 3DES and other algorithms. Encryption and decryption through hardware are currently most widely used through an encryption machine, that is, adding a hardware security module (hardware security module, HSM). [0004] Software encryption can be deployed on various computing devices, and the implementation cost is low. However, after encrypting data, the storage and management of the generat...
