摘要

硬盘加密是大容量安全存储的核心问题.基于SATA接口

提出一种桥接方式实现的硬盘加密桥设计.该设计实现了加密算法可配置

可实现对称加密的SM4和AES等算法

并能够自动检测并匹配SATA1.0与SATA2.0两种速度.重点介绍了SM4算法的实现.FPGA验证表明

计算机可以通过硬盘加密桥识别及读写硬盘.用WIN7系统的CrystalDiskMark硬盘测速软件对硬盘读写进行测速

结果表明加入硬盘桥后读速率在242MB/s以上

写速率约为160MB/s.

Abstract

Disk encryption is the core problem of large capacity safety storage.Based on SATA Interface

the paper proposes a design by building a SATA interface bridge.The design has configurable encryption-core which supports SM4 and AES.The paper mainly introduces the implement of SM4.The bridge supports SATA1.0 and SATA2.0 with automatic speed-configuration.FPGA testifies that

disk can be correctly recognized with the bridge.Speed test done by using the software CrystalDiskMark shows that read speed is above 242MB/s with the bridge in the WIN7 system.
