Welcome to polycephaly.org!

This...

... is the private website of Ruben Niederhagen. Currently, I have a postdoc position at Technical University Eindhoven in the Netherlands at the Eindhoven Institute for the Protection of Systems and Information. Previously, 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...

Polycephaly...

... is a condition of having more than one head. The term is derived from the stems poly- meaning 'many' and kephal- meaning 'head'. (Source: Wikipedia)

Parallel Architectures...

... are my topic of research and academical interest. Thus you won't find much information about multi-headed-beings on this site but tools and information about parallel computing and parallel cryptanalysis.

Any similarities...

... to the website cryptojedi.org are completely intentional and not coincidental at all.
