My name is Prof. Alexander Schinner and cryptoweb.de is my forum to make various projects I have worked on over the last few years available to the public.
As you can see, there are two topics here: "Granular Media" and "IT Security". I dealt with the simulation of granular media during my diploma and doctoral thesis, and every now and then there was a small publication on this topic. The security of IT systems is my current field of work. As I am of course bound to the highest discretion by my employer and my customers, I can only provide some presentations here that I have given at public events or congresses.
