Cryptography I

The course aims to provide an in-depth knowledge of the cryptographic algorithms and protocols widely used in real life (symmetrical, asymmetric, hash functions, KDFs, key exchange), paying particular attention to applications that protect data in-transit data, at-rest, and end-to-end.

At the end of the course the students will be able to: (1) Understand and properly use symmetric/asymmetric encryption algorithms, hash functions, digital signatures; (2) Describe and use key exchange protocols, secret sharing schemes, secure communication protocols; (3) Analyze the security of a system and the attacks known in literature: collisions of hash functions, differential cryptanalysis, attacks on implementations..
