摘　　要：设计了一种高安全性的便携式USB存储加密系统。该系统基于嵌入式USB主机CH375设计,采用智能卡实现人机安全认证和密钥的安全存储,采用反熔丝型FPGA芯片AX250高速实现3DES算法,能够在完全脱离PC机的情况下对USB存储设备中的文件进行加解密,具有很高的安全性和整体性,并可满足野外或移动应用的需求。A portable USB storage encryption system with high security is given. Based on embedded USB host CH375, realizing security authentication and secure storage of keys with smart card, and realizing 3DES algorithm high-speedly with anti-fuse FPGA AX250, this system can encrypt and decrypt the files in USB storage device without involving in a computer. Therefore, this system has very high security and performance, and can meet the needs of the field or mobile application.
