基于国产SOC的数据加密存储系统设计

Design of data encryption and storage system based on domestic SOC

针对数据信息面临的越来越严重的安全问题,提出了基于本单位自主研发的专用SOC芯片HX6801,以SD卡作为存储器,由DS3231提供实时时钟,采用Fat Fs作为文件系统的数据加密存储系统设计方案,通过对HX6801内部集成的密码协处理器和国产嵌入式CPU的编程实现数据的加密和存储。该系统充分利用了HX6801的密码处理能力及外围扩展能力,系统整体结构简单,效率比较高。

Refering to more and more serious security problems of data and information, this paper proposes a file encryption system as follows： the SOC chip HX6801 developed by our unit as core; the SD card as storage; the DS3231 chip as RTC provider; the FatFs as file system. Achieving data encryption and storage by programming integrated cryptographic coprocessors and domestic em- bedded CPU. The system takes full advantage of HX6801 cryptographic processing capability and peripheral expansion capability, this system architecture is simple and efficiency.
