Large-capacity high-security storage system supporting multiple interfaces

Abstract

The invention discloses a high-capacity and high-security storage system supporting multiple interfaces, which comprises a FLASH controller, a bus protocol processing module, a power supply configuration debugging module, an encryption module, a quick erasing module, an encryption channel controller, an FIFO cache and a FLASH storage array, and is characterized in that an SDRAM, a soft core processor and a firmware program memory are integrated in the FLASH controller; the FLASH controller communicates with the bus protocol processing module, the power supply configuration debugging module, the SDRAM, the soft core processor and the firmware program memory through an internal bus; the bus protocol processing module stores a data flow to the FLASH controller through an access channel in the FLASH controller through the encryption channel controller and the FIFO cache; and the encryption module and the rapid erasing module are connected to the FLASH storage array. According to the method, the hardware encryption function is integrated into the storage system controller, transparent encryption and decryption of data in the access process are achieved, and the safety degree of the storage system is improved.

Description

technical field [0001] The invention relates to the technical field of embedded computer system design, in particular to a large-capacity and high-safety storage system supporting multiple interfaces. Background technique [0002] Large-capacity storage systems are more and more widely used in airborne embedded systems. The storage capacity is greatly increased, the interface forms are diverse, and secret data is stored. It has the characteristics of high resource sharing, high data integration, and high software density. In addition to the functions of the disk, it also needs to have the functions of multiple interfaces, data encryption, and high-security storage. [0003] Existing storage systems cannot partition and manage data according to confidentiality levels, nor can they manage and destroy data according to confidentiality levels when necessary. Contents of the invention [0004] The purpose of the present invention is to provide a large-capacity and high-securit...
