Hello, I am Ingo Czerwinski and living in Karlsruhe, Germany. In my freetime I'm doing some mathematical research.


My main research interests are Boolean functions used in cryptography and its connections to coding theory, combinatorics and other areas. Especially cryptographically optimal functions like almost perfect nonlinear (APN) functions are in my focus.
