摘　　要：针对目前移动存储设备大量的失泄密事件,提出了一种适用于移动安全存储设备的密码SoC设计方案,并在FPGA开发板上进行了验证。该SoC集成自主设计的安全协处理器,能够支持多种密码算法。介绍了NAND Flash控制器的设计方案,并在此基础上提出了高速存取技术。基于FPGA的测试结果表明,该SoC能够有效完成多种密码操作,具有较高的数据吞吐率。基于SMIC 0.18μm工艺综合后的结果显示,工作频率能够达到100 MHz,面积约为250万门。Aiming at the vast secret leak event of removable storage devices, this paper proposed a cipher SoC design for re- movable secure storage devices,and verified it on FPGA platform.Special-designed cipher coprocessor is integrated to realize kinds of cryptographic algorithms.Then this paper introduces the architecture of the NAND Hash controller,based on which the high-speed access technology is proposed.The verification results based on FPGA platform show that this design can realize kinds of cryptographic algorithms and has high data throughput. Based on SMIC 0.18 txm standard CMOS technology, the area of our SoC is 250 million gates and can work at the frequency of 100 MHz.
