Planned learning activities and teaching methods
Teaching is carried out through lectures and seminars. Lectures consist of interpretations of basic principles, methodology of given discipline, problems and their exemplary solutions. Seminars particularly support practical mastery of subject matter presented in lectures or assigned for individual study with the active participation of students.
Assesment methods and criteria linked to learning outcomes
A written mid-term exam, a regular evaluation of projects.
Language of instruction
1. Classical cryptography.
2. Modern cryptography, symmetric and asymmetric cryptography (ciphers).
3. Symmetric ciphers. Secure algorithm features, key length, „brute force“attack.
4. Examples of symmetric algorithms (ciphers). Festal ciphers, DES, structure, operation, weak spots, and modes of operation.
5. Typical application of symmetric cryptography.
6. Asymmetric cryptography, properties, application, provided safety functions.
7. Electronic signature and its properties, hybrid cryptography.
8. Examples of asymmetric algorithms (ciphers), RSA.
9. DSS (function, attacks, affiance, optimization).
10. ElGamal, keyed hash, MAC, their application and properties.
11. Typical asymmetric cryptography application examples.
12. Key management for symmetric cryptography.
13. Key management for asymmetric cryptography (certificates, X.509).
The goal is to make students familiar with the basic concepts of applied cryptography, including classical cryptography, modern secret key and public key cryptography.
