Research & Education

Universitaet des Saarlandes (Germany), 1998, Dr.-Ing.

Universitaet Karlsruhe (Germany), 1993, Dipl.-Inform.

My research interests are in cryptography and algorithmic number theory. In the field of cryptography, my research is focused on wireless security, secret sharing, privacy, and biometrics, and my contributions range from analysis to protocol design. In algorithmic number theory, my research is centered on lattice theory, in particular on developing new algorithms and heuristics for lattice basis reduction.
