【摘要】:为满足密码模块在可信平台上的应用需求,采用高速通信接口PCI-Express与密码模块连接,从应用层到硬件层进行三点改进:在应用层中,创建密码服务函数动态库;在系统层中,对设备驱动程序进行功能扩展(实现多用户机制);在硬件层中,对传输的数据进行命令包格式封装。密码模块以DMA(directional memory access)块传输方式读取数据,实现多用户操作。实验结果表明,密码算法处理速度达到了预期的吞吐率。
[Abstract]:In order to meet the application requirement of cryptographic module on trusted platform, a high-speed communication interface (PCI-Express) is used to connect the cryptographic module to the cryptographic module, and three improvements are made from the application layer to the hardware layer: in the application layer, the dynamic library of cryptographic service function is created; In the system layer, the function of the device driver is extended (to implement the multi-user mechanism), and in the hardware layer, the transmitted data is encapsulated in the command packet format. The cipher module reads the data by the DMA (directional memory access) block transmission mode and realizes the multi-user operation. The experimental results show that the processing speed of the cipher algorithm reaches the expected throughput.
