In this paper, we review three years of development and improvements on COPACOBANA, the probably most popular, reconfigurable cluster system dedicated to the task of cryptanalysis. Latest changes on the architecture involve modifications for larger and more powerful FPGA devices with dedicated 32 MB of external RAM and point-to-point communication links for improved data throughput. We outline how advanced cryptanalytic applications, such as Time-Memory Tradeoff (TMTO) attacks or attacks on asymmetric cryptosystems, can benefit from these new architectural improvements.[pdf]
