摘　　要：文中研究了GPU计算及其在密码分析中的应用,详细分析了各自的特点和发展现状。GPU计算发展很快,具有运算密集型和高度并行的特点。密码分析的方法非常丰富,大多数方法都需要大规模的运算,而且密码运算本身也比较简单。通过理论分析并结合实例研究,发现GPU计算非常适合用于密码分析,可以大大提高密码分析特别是穷举攻击的效率。同时,也应拓宽GPU计算在密码分析中的应用,以用于更多的密码分析手段。GPU computing and its application in cryptanalysis are studied, and their characteristics and status analyzed. GPU computing, being highly intensive and parallel, develops rapidly. There are many cryptanalysis methods, and most of them require large-scale computing, while almost all kinds of crypt-computing are very simple. Theoretical analysis and research with examples expose that GPU computing is very suitable for cryptanalysis, and could greatly improve the efficiency of cryptanalysis, thus especially for brute-force attack. This paper concludes that GPU computing should extend its applications in cryptanalysis, particularly in more measures of cryptanalysis .
