一种基于Cg语言在图形处理器GPU上实现加密的方法

A NEW METHOD OF ENCRYPTION ON THE GPU PLATFORM BASED ON CG LANGUAGE

由于图形处理器GPU(Graphics Processing Unit)最近几年迅速发展,国内外学者已经将基于GPU的通用计算作为一个新的研究领域[1,2]。在研究国外最新文献的基础上,分析了美国NVIDIA公司推出的Cg(C for Graphics)开发语言本身的特性,阐述了在GPU平台上利用Cg语言编写的分组加密程序需要特殊处理的地方,最后以DES算法为实例详细描述了编程的方法和实现过程。

With the development of GPU,general computing based on GPU has become a new research field. The features of Cg program language are analyzed,and the programming model of Cg on the GPU platform is expounded. The programing and implementation method of Cg is illustrated with an example of DES encryption algorithm.
