Enciphered mobile storage apparatus and its data access method

Abstract

The utility model relates to data encryption technology, in particular to an encrypted mobile memory device and the data access method. The utility model discloses a mobile memory device that adopts hardware encryption and the data access method to strengthen the security of storing data of mobile memory devices. The technical proposal of the utility model is that: the encrypted mobile memory device comprises a USB interface, a drive circuit, a controller, a memory and an encryption chip; the USB interface, the drive circuit, the controller and the memory are connected sequentially; the encryption chip is connected with the controller; the encryption chip is used for the encryption of stored data and the decryption of read data. The utility model also discloses the data access method of the device. The utility model has the advantages that: special chip hardware encryption is adopted; the encryption algorithm is authentic and reliable; the encryption intensity is high and the secrecy is strong. Decryption data cannot be gotten even the mobile memory device is taken apart and the memory is taken out if the device is not decrypted by the encryption chip.

Description

technical field [0001] The invention relates to data encryption technology, in particular to an encrypted mobile storage device and a data access method thereof. Background technique [0002] With the rapid development of the current Internet network and mobile storage technology, computer storage media has gradually replaced paper as the main way of information storage. Mobile storage devices, including mobile hard disks (U disks), various data storage cards, etc., are widely used in government, enterprises, military and other departments. The random use of large-capacity mobile storage devices has also become a huge threat to data security. In recent years, important file loss and important information leakage incidents caused by the loss, theft, and unauthorized use of mobile storage devices are not uncommon. In some departments with computer network monitoring capabilities, such as government, enterprise, national defense and other units, mobile storage devices have ev...

Problems solved by technology

[0003] 1) The vast majority of mobile data storage devices do not have any security measures, and the holders can access the data at will

[0004] 2) Some products that use fingerprints, passwords, etc. for identity authentication have low encryption strength, and the memory can be taken out for cracking

[0005] 3) The mobile storage device does not have a reliable audit function, and cannot monitor the use of files in the device when the device is out of control or borrowed
