【摘要】:為滿足密碼模塊在可信平臺上的應(yīng)用需求,采用高速通信接口PCI-Express與密碼模塊連接,從應(yīng)用層到硬件層進行三點改進:在應(yīng)用層中,創(chuàng)建密碼服務(wù)函數(shù)動態(tài)庫;在系統(tǒng)層中,對設(shè)備驅(qū)動程序進行功能擴展(實現(xiàn)多用戶機制);在硬件層中,對傳輸?shù)臄?shù)據(jù)進行命令包格式封裝。密碼模塊以DMA(directional memory access)塊傳輸方式讀取數(shù)據(jù),實現(xiàn)多用戶操作。實驗結(jié)果表明,密碼算法處理速度達到了預期的吞吐率。
[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.
