Problems solved by technology

Portable mobile electronic devices have high requirements for the security of their stored data. The existing encryption technology has great limitations on the mobility and convenience of mobile storage devices, and increases the data reading time.
The radio frequency identification RFID encryption mobile hard disk box method currently on the market is a hardware-based radio frequency identification RFID data encoding technology. It is an intermediate link between the serial advanced technology attachment SATA and the universal serial bus USB. Encryption, this method has the disadvantage of increasing the system cost and prolonging the data transmission time

Abstract

The invention discloses a method for controlling a built-in radio frequency identification (RFID) encrypted solid-state hard disk, which comprises the following steps of: connecting all modules, then verifying whether an encryption key is accurate, finally making the encrypted solid-state hard disk enter a normal working state; after an operating system sends 'read' advanced instructions to the encrypted solid-state hard disk, reading the data subjected to error code correction and decryption through a high-speed direct memory access network; after the operating system sends 'write' advanced instructions to the encrypted solid-state hard disk, writing the processed data into one or more pages of a flash memory; and after the operating system sends 'deletion' advanced instructions to the encrypted solid-state hard disk, performing 'deletion' on the whole page through a flash memory central processing unit, and writing other un-deleted data in the page into other pages. The method has the advantages of low system cost, high stored data security and short data transmission time, is particularly suitable for portable mobile storage equipment, and can be implemented in a semiconductor chip.

Description

technical field [0001] The invention relates to the technical field of control of flash memory storage media, in particular to a control method of a solid-state hard disk with built-in radio frequency identification (RFID) encryption. Background technique [0002] The solid-state hard drive market is currently in its infancy and is about to enter a period of rapid growth, which is an inevitable trend in the development of storage technology. Traditional mechanical hard drives have become a major bottleneck in the speed of modern IT technology development. Solid-state drives have irreplaceable advantages over mechanical hard drives in terms of power consumption, performance, and mobility, which makes solid-state drives have great room for development in the field of portable mobile electronic devices. Portable mobile electronic devices have high requirements for the security of their stored data. The existing encryption technology has great limitations on the mobility and co...
