| Abstract: | 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 Algorithm 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. |
