Abstract

The embodiment of the invention discloses an encryption / decryption engine and an implementation method thereof and is applied to the technical field of information safety. The encryption / decryption engine can specifically comprise a first memory, a second memory, an encryption / decryption module and an SATA (Serial Advanced Technology Attachment) hard disk drive interface, wherein one end of the first memory is connected with the SATA hard disk drive interface and the other end of the first memory is connected with the encryption / decryption module; the second memory is connected with the encryption / decryption module; one end of the encryption / decryption module is connected with the first memory and the other end of the encryption / decryption module is connected with the second memory; and one end of the SATA hard disk drive interface is connected with the first memory and the other end of the SATA hard disk drive interface is connected with an SATA host interface of a mainboard. By means of the implementation method of the encryption / decryption engine, provided by the embodiment of the invention, the encryption / decryption module which is safer, more reliable, higher in performance and better in compatibility can be provided for information safety service providers.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an encryption / decryption engine and its implementation method. Background technique [0002] The encryption / decryption engine is a module that provides users with encryption and decryption services, which can be realized through software solutions or hardware solutions. The hardware solution can be implemented by using a USB interface, or can also be implemented by using a PCI or PCIE interface. The algorithms implemented by the encryption / decryption engine include symmetric algorithms, asymmetric algorithms and digest algorithms. Symmetric algorithms include SM1, AES, and SM4; asymmetric algorithms include SM2, RSA; digest algorithms include SHA1, SHA256, and SM3. Symmetric algorithms are generally used for data encryption and decryption; asymmetric algorithms are generally used for identity authentication and access control. The encryption / decryption engine gene...
