Cluster of Excellence CASA

In the CASA Cluster of Excellence, we are interested in information-theoretical modeling, analysis and optimization of cryptographic basic functions in future communication and data processing networks.
The precise modeling of real communication channels and communication scenarios plays a central role.

We are especially focused on:

  • operationally based information-theoretical security measures such as semantic security
  • wiretap channels with and without attackers
  • bit commitment, oblivious transfer via real communication channels and real communication tasks

On the CASA homepage of the Ruhr-Uni-Bochum (RUB) you will find all information about the project CASA: Cyber Security in the Age of Large-Scale Adversaries.

J.A. Cabrera, H. Boche, C. Deppe, R.F. Schaefer, C. Scheunert and F.H.P. Fitzek wrote a book chapter 6G and the Post-Shannon Theory in the book Shaping Future 6G Networks
