基于CUDA的高效IDEA加密算法设计与实现

摘要

为了实现一个高效的加密算法,本文充分利用图形处理器(GPU)的并行处理能力,提出基于CUDA实现IDEA加密算法的方法,对该方法的设计和实现进行详细的阐述,并通过实验与传统的基于CPU的实现方法进行性能比较,基于CUDA的IDEA实现速度上远远高于基于CPU的实现.%With the parallel processing capability of Graphics Processing Unit (GPU) , design and implementation of IDEA algo-rithm is proposed as an efficient encryption and decryption algorithm, which is elaborated in this paper. Both traditional CPU-based and new one based on GPU are implemented. At last, the performance based on GPU is analyzed, which runs much faster than the traditional approach.
