Research
I am a postdoc in the crypto group which is part of the
Department of Mathematics (DTU mathematics)
at the Technical University of Denmark (DTU) in Denmark.
My PhD-thesis is entitled "Cryptanalysis of Lightweight Ciphers" and can be found here.
My research interests are symmetric cryptography and cryptanalysis. In particular I am intested in
- Cryptanalysis using optimization
- Cryptanalysis of ciphers with secret components
- Lightweight cryptograph
Currently my main focus lies on the use of optimization in cryptanalysis. This project is supported by the Danish Council for Independent Research, Technology and Production Science.
See here for further information on the project.
