Performance Evaluation of Blowfish Algorithm on Supercomputer IMAN1

摘要

Cryptographic applications are becoming increasingly more important in today’s world of data exchange,big volumes of data need to be transferred safely from one location to another at high speed. In this paper,the parallel implementation of blowfish cryptography algorithm is evaluated and compared in terms ofrunning time, speed up and parallel efficiency. The parallel implementation of blowfish is implementedusing message passing interface (MPI) library, and the results have been conducted using IMAN1Supercomputer. The experimental results show that the runtime of blowfish algorithm is decreased as thenumber of processors is increased. Moreover, when the number of processors is 2, 4, and 8, parallelefficiency achieves up to 99%, 98%, and 66%, respectively.
