Fundamentals in Cryptography and Network Security

The course aims to provide the fundamental notions of cryptography, introducing the main cryptographic primitives and their properties, as well as application examples. Furthermore, the course presents in a critical perspective, the principles underlying the security of computer systems and analyzes the threats to which computing systems in TCP/IP networks are exposed and the possible countermeasures.

At the end of the course, the student will have to know the main cryptographic primitives, know the most widespread threats both at the local network level and at the infrastructure level and be able to: discuss and design the security of networked systems; analyze TCP/IP protocols from a security perspective; analyze traffic and recognize attacks; critically use the major defense technologies such as firewalls and network intrusion detection systems;
