Parallel performance of DES in ECB mode

This study presents the design and implementation of DES encryption in ECB (electronic codebook) mode under three different parallelization schemes. The first method we suggest is block based, where 64-bit blocks of text are distributed among the parallel processors. The second approach is pipeline based, where we parallelize each of the 16 internal rounds of DES. The third parallelization scheme is plaintext based which divides the plaintext into equal partitions first and then assigns the 64-bit blocks of each partition to parallel processors. We obtained runtime performances for each parallelization. To observe whether the source language has an effect on the overall performance, we run our algorithm on text from 5 different languages as English, French, German, Spanish and Turkish
