Contribution of the course to the overall degree programme goals
This course aims at introducing basic concepts of Cryptography and some of its applications. The student will acquire some skills needed to protect both data inside a system and data that are communicated inside a network.
Expected learning outcomes
Frequency and active partecipation to the proposed training activities (lectures, exercises) and the individual study, will let students:
1 Knowledge and understanding
1.1. acquire the theoretical foundations of cryptography;
1.1. acquire knowledge of some practical applications of cryptography.
2. Ability to apply knowledge and understanding
2.1. know how to use the knowledge acquired to develop secure systems based on cryptographic codes,
3. Ability to judge
3.1. know how to choose and analyze the most appropriate cryptographic model in a specific real context.
The course requires some background in mathematics, probability, statistics, algorithms, programming.
2. Classical cryptography
2.1 Monoalphabetic ciphers
2.2 A formal definition of cryptosystem
2.3 Polyalphabetic ciphers
2.4 Known-plaintext attacks
2.5 Stream ciphers
2.6 Shannon theory on perfect ciphers
3. Modern cryptography
3.1 Composition of ciphers
3.2 The Advanced Encryption Standard (AES)
3.3 Block cipher modes of operation
3.4 More block ciphers
3.5 Meet-in-the-middle attack
3.6 Asymmetric-key ciphers
3.7 The RSA cipher
3.8 Security of RSA
3.9 Digital signatures, cryptographic hash functions and MACs

The verification of the knowledge is done through the passing of a written exam. The oral exam is compulsory for those who are almost sufficient (between 15 and 17), optional for those which have a sufficient grade. The written exam (and the eventual oral exam) are required to verify the knowledge of the course contents. For those that attend classes we will also offer two partial exams, one in the middle of the course and one after the end of the course (that can be taken only by passing the first part). Passing both parts will allow the student to be exonerated from the global written exam.
