Abstract

Cryptanalysis of symmetric and asymmetric ciphers is computationally extremely demanding. Since the security parameters of almost all practical crypto algorithms are chosen such that attacks with conventional computers are computationally infeasible, the only promising way to tackle existing ciphers (assuming no mathematical breakthrough) is to build special-purpose hardware. This contribution presents a special-purpose hardware labeled COPACOBANA (cost-optimized parallel code breaker), which is optimized for running crypt-analytical algorithms with low communication overhead. The price-performance ratio as primary and a cost margin of less than US$ 10,000 as secondary design goal led to a reconfigurable computer built as cluster of programmable logic devices
