# PhD Thesis

I defended my PhD on December 13, 2013 at the math department of the University of Basel.

My thesis, entitled **Trace zero varieties in cryptography: Optimal representation and index calculus**, was published by the University of Basel under DOI 10.5451/unibas-006246470.

In Chapter 3, I promised to make some equations of the trace zero variety available online.

The thesis and the equations can be downloaded here:
