This is an implementation of the PRESENT lightweight block cipher as described in this paper. It encrypts individual blocks of 64 bit length with an 80 or 128 bit key. The desired key length can be set via the generic k (either K_80 or K_128).

The Vivado project file (*.xpr) is configured to use the Digilent Zybo FPGA board for synthesis. This board is not available by default in Vivado (at least not if you are using the WebPACK edition). To obtain the required board files for the Zybo (and other boards by Digilent), refer to this wiki entry.
