Welcome to polycephaly.org!
This...
... is the private website of Ruben Niederhagen.
Currently, I am researcher at the
Fraunhofer Institute for Secure Information Technology.
Previously, I was postdoctoral researcher at
Technical University Eindhoven
in the Netherlands at the
Eindhoven Institute for the Protection of Systems and Information.
Before that, I had a postdoc position at
Academia Sinica in Taiwan at the
Institute of Information Science.
This site is intended to
give access to my research results and to stuff which I
consider of interest and which I would like to share
with you.
You are welcome to contact me via mail at 
on my research topics...
