The program of the course can be downloaded here cryptoprogram.pdf
Italian version: programma-critto.pdf

A list of the topics taught in every lecture is here:

Addenda on the following topics: some historical example (Caesar, Poe, Verne), the schemes for DES and AES.

These notes are written partly in Italian partly in English; unfortunately I had no time to completely translate them in English. I hope that students from abroad can understand such examples as well.


I will use my books

An exaustive bibliography, and some suggested supplementary readings, can be found in the mentioned book.

It's a written exam containing questions about the topics explained during the course. To be inserted in the list of the exam, one should connect to UNIWEB and look for the italian name of this course (i.e. "Crittografia"). To be able to have his/her exam, it is mandatory that the student has subscribed to the uniweb exam list and that he/she comes to the exam class with an identity document with picture included (e.g. an italian identity card or a passport for people coming from abroad). If at least one of the previous conditions will not hold, the student will be asked to leave the exam class. The marks of the exam will be (unofficialy) available on my web page. In a day that will be communicated together with the marks, the students will have the possibility to see their corrected exams and to discuss with me about the corrections. After this their marks will be officially communicated again via Uniweb; after this communication the students will have to accept or refuse their marks (via uniweb) within 7 days (Regolamento Carriere Studenti, art. 22, comma 14, Decreto Rettorale 1371-2014); see this modification . If a student will not accept or refuse his/her mark, than he/she will have to repeat the exam in a next session.
