摘　　要：大数据时代,数据安全面临着巨大的挑战。由于网络通信和存储的数据规模急剧增加,大量的密码运算会影响系统的性能,如何快速地对数据进行密码运算是数据安全中的重点问题。SHA1是一种常见的密码杂凑算法,主要用于数字签名、文件的完整性检验等,广泛应用于互联网的各个方面。密码杂凑算法的运行时间是与文件大小成正比的,所以计算大文件的消息摘要十分耗时。为了进一步提升SHA1的性能,文章基于GPU技术,实现对密码杂凑算法SHA1的加速运算,运算速度达到791GB/s,相比于现有的加速方案性能有明显的提升。In the era of big data,data security is facing enormous challenges.Due to the rapid increase of network communication and data storage,a large number of cryptographic operations will affect the performance of the system,how to quickly perform cryptographic operations on data is a key issue in data security.SHA1 is a common cryptographic hash algorithm,which is mainly used for digital signature,file integrity checking and so on,widely used in all aspects of the Internet.The running time of cryptographic hash algorithm is proportional to the file size,so it is very time-consuming to calculate the message summary of large file.To further improve the performance of SHA1,based on the GPU technology,this paper achieves the acceleration operation of SHA1,a cryptographic hash algorithm,with a speed of 791 GB/s.Compared with the existing algorithms,the performance of the algorithm has been significantly improved.
