摘　　要：大数据时代对敏感数据的保护需求与日俱增，如何在安全可控的软硬件环境下进行大数据集处理成为一个研究热点。设计了一种基于安全可控国产X86处理器的大数据平台，利用AES（Advanced Encryption Standard）算法对海量敏感数据提供安全保障；并合理构建GPU畀构计算环境，充分提高国产大数据平台的分析计算效率，为海量数据的安全处理提供了全新的解决方案。实验结果表明，基于国产兆芯X86处理器的GPU异构计算平台能有效满足大数据集处理需求；通过改进异构计算环境下的AES算法提升了加密效率，并获得了22-23倍的加速比。当应对海量数据（GB级以上）时，国产异构计算平台的并行处理能力和加速效果非常明显。该研究结果对有海量敏感信息的大数据集处理和信息安全保护具有重要应用价值。With the needs of sensitive data protection growing in the era of big data,how to handle big data sets has become a hot research topic under the safe and controllable hardware and software environment. This paper designed a safe and controlled domestic X86 processor-based big data platform,which provides security for massive sensitive data by using AES （Advanced Encryption Standard） algorithm. In addition, we reasonably constructed the GPU heterogeneous computing environment, thereby fully improving computational efficiency of the domestic big data platform, which provides a new solution for the safe handling of massive data . Experimental results show that domestic x86 processor （ZHAOXIN）-based GPU heterogeneous computing platforms can effectively meet the needs of big dataset processing. The improved AES algorithm to adapt heterogeneous computing environment can enhance the efficiency of encryption, and gain 22 to 23 times speedup. Dealing with massive data （GB and above）, parallel processing capabilities and acceleration effect of domestic heterogeneous computing platform are very clear. The results of massive sensitive data processing and information security have important application value.
