Major research topics of his group are cryptographic and cryptanalytic implementations and systems, in particular involving reconfigurable devices. With respect to cryptographic implementations, he established and still holds performance records for the symmetric AES-128 block cipher on Xilinx Virtex-5 FPGAs and asymmetric Elliptic Curve Cryptography standards on Xilinx Virtex-4 FPGAs. He co-developed the COPACOBANA FPGA cluster system in cooperation with the University of Kiel that was originally designed to tackle the vast amount of complex computations for a large variety of cryptanalytic applications. Due the great success of this unique cluster system, it is now sold world-wide by the spin-off company Sciengines GmbH.
