Design of hard disk data encryption system in Ultra DMA mode and its implementation using FPGA

Guanzhong Dai

Abstract

This paper presented the design of hard disk data encryption system based on FPGA.This encryption system ran in Ultra DMA mode,and it was encryption core supports AES,DES,3DES and other kinds of symmetry-key encryption algorithms designed by users.According to the result of testing,the system steadily work at the speed of 32 Mbps in Ultra DMA model 2 without any influence on computers fuction.
