基于 Android 手机软件认证的U盘锁系统

摘要

To improve the security of USB memory stick, this paper designs a U-disk locking system using the Android software certification based on a mobile phone. This paper introduces the security breaches existing in the process of using U-disk, discusses the composition and the working process of the system , and analyzes the system implementation. This paper develops a mobile control software (AC) and a control program of the locked U-disk (UK), gives flowcharts of AC and UK. Finally, by using an Android-based mobile phone as a unlock controller and using another Android-based mobile phone as a simulator of the locked U-disk, the system function is tested. The test results show that the design of the system achieves the desired objective with the good security. simplicity and practicability, laying a good foundation for the practical use of the U-disk locking system.%为提高 U 盘使用的安全性，文章设计了一种基于 Android 手机软件认证的 U 盘锁系统。介绍了 U 盘使用过程中存在的安全隐患，讨论了该系统的构成及其工作过程，分析了该系统实现方案。文章还开发了手机控制软件（AC）及加锁 U 盘控制程序（UK），给出了 AC 及 UK 的工作流程图。最后，以一部 Android 手机作为 U 盘开锁控制器，以另一部 Android 手机模拟加锁 U 盘，进行了系统功能测试。测试结果表明，该系统达到了预期的设计目标，且其保密性好、操作简便、实用性强，为 U 盘锁系统的实用化打下了良好的基础。
