基于USB2.0的硬件密码组件的设计与实现

Design and Implementation of Hardware Cryptographic Module Based on USB2.0

本文提出了一种硬件密码组件的设计及具体实现方法,其中包括硬件结构、固件设计方案、驱动以及其应用程序的实现。该系统采用ADSP数字信号处理器和EZ_USB CY7C68013设备接口芯片来实现系统与PC机之间的高速数据传输,提出了一种使用软硬件技术开发符合USB2.0规范的硬件密码组件的方法。

The paper proposes a design and implementation of Hardware Cryptographic Module, it includes the frame of hardware, the de- sign of the firmware, its driver and its application. ADSP and EZ_USB CY7C68013 interface chip are used in this system to realize the high speed data transmission between it and PC, and a Hardware Cryptographic Module, using software and hardware, is presented according to the USB2.0 criterion.
