As the example of COPACOBANA [105] shows, key-search machines need not be prohibitive from a monetary point of view. We now consider a simple bruteforce attack on DES which runs on COPACOBANA.

1. Compute the runtime of an average exhaustive key-search on DES assuming the following implementational details:
COPACOBANA platform with 20 FPGA modules

6 FPGAs per FPGA module

4 DES engines per FPGA

Each DES engine is fully pipelined and is capable of performing one encryption per clock cycle
100 MHz clock frequency
