Performance Evaluation of Blowfish Algorithm on Supercomputer IMAN1

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 of running time, speed up and parallel efficiency. The parallel implementation of blowfish is implemented using message passing interface (MPI) library, and the results have been conducted using IMAN1 Supercomputer. The experimental results show that the run time of blowfish algorithm is decreased as the number of processors is increased. Moreover, when the number of processors is 2, 4, and 8, parallel efficiency achieves up to 99%, 98%, and 66%, respectively. Keywords—Blowfish; Encryption; MPI; Supercomputer
