加密U盘的设计与实现

USB移动存储设备,由于其突出的优点得到广泛的应用。但普通USB存储盘安全性能低,不适合用来存储敏感信息。本文在研究强制口令认证、数据加密等安全防护技术的基础上,提出一个基于普通U盘的安全解决方案。本方案在完成一个普通U盘设计的基础上,设计口令认证机制和基于分组算法的数据存储加密机制,论述实验中的相关问题并给出了部分实现过程,该方案可有效提高U盘的安全性能。

USB flashy storage equipment is widely used because of its advantages, while common USB storage equipments are low in safety and not suitable for the storage of some confidential messages. The paper is offering a safety - solving project based on common U disk after the research on the techniques such as confirmation of the password and pinned data and the like. The project is to design the system of the password confirmation and the pinned data based on the mathematics and discusses on the relevant problems in experiment and part of the achievement. In all , the project is to promote the security function of U disk efficiently.
