Abstract: Secure storage has become the concern of researchers in the information security domain in succession to secure communications.A hardware encryption scheme for USB mobile hard disk drive based on FPGA is designed and implemented,which adopts smart cards with built-in functions for security computation to carry out authentication as well as key acquisition and proposes a data integrity verification method working at the cluster level.Experimental results show significant improvement in system security and data access speed.The design can be applied to prevent information leakage caused by losing,stolen and disuse cases and illegal data modification of mobile hard disk drives.

摘要: 安全存储是继通信保密问题之后信息安全领域的一个研究热点。设计并实现了一种基于FPGA的USB移动硬盘硬件加密方案,提出了一种采用具有安全计算功能智能卡的双向认证和密钥获取技术及一种簇级别的数据完整性验证方法。实验结果表明,系统在安全性和读写速率方面均具有较大提升,可用于防止因移动硬盘丢失、被盗、废弃引起的泄密问题及对数据的非法篡改。
