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.
