Cryptography and Formal Methods of IT-Security
Students receive a general overview of formal methods of security in distributed information systems and the central ideas and concepts of cryptography that were acquired in the Bachelor module IT Security are deepened and extended.
In particular, they master the mathematical principles, theories and functions of cryptographic methods. The students are able to assess protocols of encryption, authentication and key exchange, to apply them to solve complex problems and to extend and evaluate the practical implementation if required.
Furthermore, students are familiar with selected access control systems and have the ability to develop an information security and management system. They are prepared to use their knowledge to react creatively to new circumstances. The students are able to define goals and solutions in professional practice and in academic contexts for communication security and information assurance.
