    Information Systems and Network Security (6 CREDITS). Link to the Computer Science Degree official website (click here).
    Description: The goal of this course is to provide students with an overall understanding of the main concepts of information systems and network security. The first part of the course deals with network security and in particular cryptography. The second part of the course focuses on information systems and in particular on some algorithmic issues arising in information systems. Topics include:
  • Basics of cryptology: introduction;
  • Basics of cryptology: symmetric cryptography, hash functions, asymmetric cryptography;
  • Introduction to Information Systems, introduction to cloud computing;
  • Algorithmic issues arising in information systems: envy-free scheduling;
  • Algorithmic issues arising in information systems: revenue maximization envy-free pricing problems.
    Timetable: First semester (October 5, 2020 - January 22, 2021), Wednesday: 10.10 - 11.50 (room A1.1 and Online), and Thursday: 10.10 - 11.50 (room A1.1 and Online).
    Name of the Team: INFORMATION SYSTEMS AND NETWORK SECURITY.
