| 摘 要： | 针对目前移动硬盘加密系统中存在的数据泄露,更改密钥不灵活等问题,本文提出了基于FPGA的移动硬盘数据加密系统—AES系统。该系统不仅能实现对移动硬盘数据的实时加密,而且还可以根据需要随时更换密钥,并且在加密结束后及时销毁FPGA中的密钥。实验结果说明,该系统可以提高数据的加密效率、安全性和可靠性,经过QuartusII 11.0软件优化后,使程序占总资源仅为53%,提高了资源的利用率。

| Abstract: | At present,in order to solve the data leakage of a hardware encryption system for mobile hard disk,the changing key is not flexible and so on. The hardware encryption system for mobile hard disk based on FPGA —AES system is designed. The system not only achieves the real-time encryption for the data of the mobile hard disk,but also modifies the key according to the need. Meanwhile,it can destroy the key after finishing the process of encryption.Experimental results show that the system improves the efficiency,the security and the reliability of data encryption.What＇s more,the procedure takes up 53% in general resource by the optimization of the QuartusII 11.0 software tools,which enhances the resource utilization ratio. |
