摘要

本文考察了CUDA技术在加密算法与公钥并行化中的应用效率。比较了几种算法的执行速度:CPU上的顺序实现和CPU和GPU上的两个并行实现。给出了公钥算法的描述,以及允许其并行化的属性。分析了并行实现的优缺点。结果表明,它们中的每一种都适用于不同的场景。开发了软件,并进行了数值实验。验证了所得到的加解密结果的可靠性。为了消除执行时外部因素的影响,算法连续测试了10次,并计算了平均值。基于OpenMP和CUDA技术估计了消息加解密算法的加速系数。提出的方法侧重于通过开发计算机系统和图形处理器的多核架构的前景进一步优化的可能性。

PARALLELIZATION OF RSA CRYPTOGRAPHIC ALGORITHM BASED ON CUDA TECHNOLOGIES
The paper examines the efficiency of the application of CUDA technologies for the parallelization of the cryptographic algorithm with the public key. The speed of execution of several implementations of the algorithm is compared: sequential implementation on the CPU and two parallel implementations – on the CPU and GPU. A description of the public key algorithm is presented, as well as properties that allow it to be parallelized. The advantages and disadvantages of parallel implementations are analyzed. It is shown that each of them can be suitable for different scenarios. The software was developed and several numerical experiments were performed. The reliability of the obtained results of encryption and decryption is confirmed. To eliminate the influence of external factors at the time of execution the algorithm was tested ten times in a row and the average value was calculated. Acceleration coefficients for message encryption and decryption algorithms were estimated based on OpenMP and CUDA technology. The proposed approach focuses on the possibility of further optimization through the prospects of developing a multi-core architecture of computer systems and graphic processors.
