Abstract: 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 heteroge-neous 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 accelera-tion effect of domestic heterogeneous computing platform are very clear.The results of massive sensitive data proces-sing and information security have important application value.
