Abstract

The invention discloses a data encryption and decryption device and an encryption and decryption method thereof. The data encryption and decryption device comprises a device body, an encryption deviceand a decryption device. The encryption device comprises a data receiving module, a data analysis module, a data judgment module, a microprocessor, a key selection unit, an encryption module, a storage module and a data sending module. The decryption device comprises a database, a determination module, a search module, a call unit, a decryption request module, a decryption algorithm request unit,a decryption module and an output unit. The encryption device and the decryption device are connected through adoption of an RS232 interface or an RS485 interface. In order to ensure the security ofdata, a level of the data is analyzed according to the data analysis module, an encryption method of the data is selected through adoption of the key selection unit, the data is enabled to obtain an encryption method only applicable to related data, the data decryption device searches an encryption mode of the data through adoption of the search module, a corresponding decryption algorithm is called through adoption of the call unit, and the decryption speed is accelerated.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a data encryption and decryption device and an encryption and decryption method thereof. Background technique [0002] Nowadays, the world has entered the information age, and the computer network has developed rapidly, which is related to all aspects of social life. However, while enjoying the convenience brought by the Internet, we also face many problems. One of the most prominent problems is the problem of network information security. In order to solve the problem of network information security, people often use data encryption to protect network information. Data encryption refers to the conversion of plaintext into ciphertext through encryption algorithms and encryption keys to realize information concealment, thereby protecting information security. [0003] Conventionally, in magnetic disk devices, optical disk devices, and other memory devices, in order ...
