Learning objectives:
  Students are introduced cryptographic mechanisms and their implementations. The goal is to acquire knowledge about cryptography (algorithms as well as protocols). Attention will be given to flaws  during their implementations and possibilities to attack real-world implementations of cryptographic algorithms arising from specific properties of physical realisations.
  Introduction to cryptography, real-world (commercial) use / exploitation of cryptography, types of device used for running cryptographic mechanisms and protocols, descriptions of fundamental (not only) electrical properties of IT devices. Analysis of cryptographic algorithms, classification of cryptographic mechanisms according to typical implementation flaws. Statistical  processing of information obtained from real devices, possible usage of the information, estimating information value of covert channels. Countermeasures - how to eliminate covert channels, economical requirements of cryptography implementations.

Knowledge and skills required for the course:
  Operating systems, assemblers, algebra, number theory, network protocols.
Learning outcomes and competencies:
  Overview of practical issues and problems of using cryptographic mechanisms in real-world systems.
