摘　　要：随着U盘、移动硬盘等USB类移动设备在信息存储和交换应用中应用的普及,由于使用和管理不当引发的信息安全问题层出不穷,本文基于动态口令(One Time Password,OTP)加密体制,采用STC51设计了一款“一次一密”安全U盘。该安全U盘包括动态口令卡、无线遥控器和安全U盘三部分,动态口令卡生成一次性密码,用户通过无线遥控器输入动态密码,安全U盘接收到正确的无线密钥后开启U盘读写权限。通过实验验证,安全U盘能够有效地通过技术手段将安全隐患降低。With the popularity of USB mobile devices such as U-disk and mobile hard disk in information storage and exchange applications,information security problems caused by improper use and management emerge in endlessly.Based on OTP(one-time password)encryption system,this paper designs a"one time one secret"security U-disk using STC51.The security USB flash disk consists of three parts:dynamic password card,wireless remote control and USB flash disk.The dynamic password card generates a one-time password.The user inputs the dynamic password through the remote control.After receiving the correct wireless key,the security USB flash disk opens the read-write permission of USB flash disk.Through the experimental verification,this work can effectively reduce the security risks of U-disk in the management and use to the minimum through technical means.
