| Abstract | Computer security relies on cryptography as a means to protect the data that we people have become increasingly reliant on. The main research in computer security domain is how to enhance the speed of RSA algorithm. The computing capability of Graphic Processing Unit as a co-processor of the CPU can leverage massive-parallelism. CUDA and OpenCL are the two programming interfaces used for this purpose. CUDA is specific to NVIDIA GPU's and OpenCL provides a portable language that can program CPU, GPU and other devices from different vendors too. This paper presents RSA algorithm as a source for comparing the performance of CUDA and OpenCL. First the traditional algorithm is studied. Secondly, the parallelized RSA algorithm is designed for both Nvidia CUDA and OpenCL framework. Thirdly, the designed algorithm is realized for small and large prime numbers on CUDA, OpenCL and C and performance gap is concluded. So, the main fundamental problem of RSA algorithm such as speed and use of poor or small prime numbers resulting in significant security holes, despite the RSA algorithm's mathematical soundness can be alleviated by GPU programming. Decision depends which programming interface is to use depending upon the various factors such as prior familiarity with the existing system, availability of development tools to target the GPU hardware, performance and portable programming language. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
