摘　　要：作为一种通信接口规范,通用串行总线(USB)因其具有传输速度快、可靠性高、使用灵活等优点被广泛应用在PC外设和便携式系统中。本文研究了将排列码算法应用于加密USB移动硬盘系统的设计方案,提出采用ALTERA公司的Maxplus II设计此算法的专门功能部件来提高数据传输加密/解密速度,解决了数据传输过程中的加密/解密速度慢的瓶颈问题,实现了一种具有加密功能且传输速度快的USB移动硬盘系统。Universal Serial Bus （USB）, as a communication interface specification, is widely applied to external-device and portable system. The advantages of USB are high-speed data transfer, high reliability and the versatility in application. The design using Permutation Code Algorithrn in encrypted USB portable hard disk was studied. The results show that it could improve algorithm speed of encrypt and decrypt with specialized function device designed by Maxplus II, ALTERA corporation. Using the design, the bottleneck of encrypt and decrypt speed in data transmission process can be solved, and the encrypted USB portable hard disk system with higher speed can also be achieved.
