• Type: VU Lecture and Exercise
• Format: Hybrid

## Learning outcomes

After successful completion of the course, students are able to understand the fundamental concepts in cryptography, used for encryption and authentication. They are familiar with the basic definitions in symmetric and public-key cryptography as well as the principle of provable security, the paradigm of modern cryptography. They have seen the most important constructions of cryptographic objects and several security proofs. In the exercises they have learned how to argue about the security of schemes. This course is a good basis to study advanced topics like cryptographic protocols.

## Subject of course

• Information-theoretic security
• Computational security
• Private-key encryption
• Message authentication codes
• Hash functions
• Public-key cryptography
• Digital signature schemes

## Teaching methods

Presentation with slides via Zoom; homework assignments, presentation of the solved assignments, guided discussions.
