To give the student knowledge about cryptanalytic methods in symmetric encryption (block ciphers and stream ciphers) and hash functions.

• explain the ideas of linear cryptanalysis, higher order differential attacks, truncated differential attacks, impossible differential attacks, and interpolation attacks on block ciphers
• explains the concepts of collision attacks, preimage attacks and of multi-collisions for hash functions
• explain the ideas of time-memory tradeoff, correlation, algebraic, and linear distinguishing attacks and their application to stream ciphers
• apply presented methods on toy ciphers
• evaluate critically the presented topics from a technical-scientific point of view
• make an oral presentation of a selected scientific article
• search the scientific literature for further information in relation to the selected article
• act as an active listener at scientific seminars

Block ciphers: linear cryptanalysis, higher order differential attacks, truncated differential attacks, impossible differential attacks, interpolation attacks.
Hash functions: collision attacks, preimage attacks, multi-collisions, the SHA3 competition.
Stream ciphers: time-memory-tradeoff attacks, correlation attacks, algebraic attacks, linear distinguishing attacks.
