What to know for the exam? • Basically the things that are on the slides. • We will not go into details of proofs. • E.g. you should know what a cryptographic hash function is, how symmetric and asymmetric encryption work in general, how block ciphers work, what happens in a chosen plaintext attack, etc. • You do not have to attend the lectures. You can also just go through the slides. We will not check the attendance in the lecture.
