Impact of the DES and AES Algorithms on PERS (A Specific Processor for Sensor Networks)

This paper presents a specific processor for sensors networks (PERS), in a first approach, we used the point-to-point topology. We highlight its architecture, its limited instruction set, simulations and performance results when executes the AES and DES algorithm. We have implemented several versions of our PERS in FPGAs, our first version (simple processor) and finalize with our fourth version, which insert special instructions for the AES and DES algorithms.
