Abstract

The invention discloses an encryption / decryption device and method, and belongs to the technical field of secure data storage. The device comprises a master control security chip (1), a first USB interface (2), a second USB interface (3) and a rechargeable battery (4), wherein personal identification codes are stored in the master control security chip (1); the first USB interface (2) and the second USB interface (3) are respectively connected with the master control security chip (1); the rechargeable battery (4) is used for supplying power to the device; and the rechargeable battery (4) is connected with the master control security chip (1). By adopting the encryption / decryption device and method provided by the invention, encryption / decryption operation can be carried out on the data in the terminal equipment such as PCs or mobile phones, and the encrypted data cannot be accessed without the participation of the encryption / decryption device, so that the security of the data stored in the terminal equipment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of data security storage, in particular to an encryption and decryption device and method. Background technique [0002] At present, with the rapid development of electronic devices, users generally store the same data file in different electronic devices. For example, the data stored in a PC is also stored in their own mobile phones to facilitate data storage Check it anytime. And users pay more and more attention to the security of their private data, important documents, confidential information and other information, and do not want unauthorized individuals or organizations to access and read these information. Although the user can use encryption software to encrypt and store the data, criminals can still crack the encrypted data after the mobile phone is lost or stolen. Therefore, there is an urgent need for a good encryption and decryption method, so that even if criminals steal the user's mobile ph...
