摘要
针对信息安全领域中敏感数据的安全存储及加密协处理应用需求,设计了基于PCI-E总线的高速数据加密卡。在方案中以FPGA为载体,实现了AES加密算法及32位CRC校验算法;提出了一种高效的DMA传输结构,提高了总线利用率和数据传输速率。实践表明本设计具有加解密速度快、安全性高和通用性好的特点。
The design and implementation schemes of a high-speed PCI Express bus-based data encryption card which aims at the applied demands of preventing illegal data duplication and encryption co-processing is introduced in detail. It implemented the AES encryption algorithm as well as a 32-bit CRC on the FPGA platform and proposed a highly efficient DMA transfer scheme which significantly improved bus efficiency and data transfer rate. The design possesses the characteristics of favorable encryption speed, high security level and prevalent applicability.
