Cryptanalysis of symmetric and asymmetric ciphers is computationally extremely demanding. Since the security parameters (in particular the key length) 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(More)
In this paper we present new approaches to high performance protein database scanning on two novel massively parallel architectures to gain supercomputer power at low cost. The first architecture is built around a Beowulf PC-cluster linked by a high-speed network and fine-grained parallel Systola 1024 processor boards connected to each node. The second(More)
The computational fundament of most public-key cryptosys-tems is the modular multiplication. Improving the efficiency of the modular multiplication is directly associated with the efficiency of the whole cryptosystem. This paper presents an implementation and comparison of three recently proposed, highly efficient architectures for modular multiplication on(More)
Cryptanalysis of symmetric and asymmetric ciphers is a challenging task due to the enormous amount of involved computations. To tackle this computational complexity, usually the employment of special-purpose hardware is considered as best approach. We have built a massively parallel cluster system (COPA-COBANA) based on low-cost FPGAs as a cost-efficient(More)
