• Basics of Cryptology.
• Game Theory for Network Security (if there is time)
• Introduction to Information Systems.
• Algorithmic Issues arising in Information Systems: Revenue Maximization Envy-Free Pricing Problems.
• Algorithmic Issues arising in Information Systems: Scheduling Algorithms; Envy-Free Scheduling.
  Timetable: First semester (September 18, 2017 - December 22, 2017), Wednesday: 11.30–13.30 (room A1.2) and Thursday: 9.30–11.30 (room A1.2)
  Students’ reception: After the lectures or by appointment. Given that I could be out of the office due to academic or research commitments, students are invited to arrange the day and time of the meeting by e-mail and therefore to send an e-mail preventively.
  Course Material: Lecture notes (slides) provided by the lecturer. Plus the extra didactic material (please do not hesitate to contact me if you have problems with finding them).
