One important requirement imposed on all eSTREAM stream cipher candidates was to show the potential to be superior to the AES in at least one significant aspect. We present hardware implementation results of eight different e Stream Profile-II candidates, all integrated in 0.25 um 5-Metal CMOS technology. The goal of this work was to provide a fair base for comparision of different hardware crypto algorithms. Additionally, an AES core optimized for stream cipher output has been implemented and is listed as comparative reference.
With the feedback from the SASC 2006 conference we have compiled the following white paper:
