摘　　要：为防止涉密信息通过存储介质泄露,以实现存储介质上信息可靠清除为目标,基于具有SATA、IDE、USB接口的嵌入式系统,设计实现了可对硬盘、U盘等实现不同可靠度数据清除的数据粉碎机。模块化的设计便于增减数据粉碎机的处理能力,不同的数据清除模式可在处理耗时与清除的可靠度间取得平衡。测试表明数据粉碎机各项功能正常,稳定可靠。For the purpose to prevent confidential information being divulged through storage medium,the paper designed a machine that can clean the data in hard-disk or flash-disk at different reliability of erasing data,and that bases on the embedded system that possesses SATA,IDE and USB interfaces.The processing capability of the machine can be increased or decreased conveniently because the machine is modular.The time-consuming of erasing data and corresponding reliability of erasing data in different processing mode can be balanced.All functions of this machine are achieved and it works well and stably in the test to it.
