OVERVIEW

This is an introductory course in Coding Theory and Cryptography.

A large part will be dedicated to the mathematical aspects of Coding Theory which studies the problem of correcting errors in messages transmitted through a non secure channel with noise.

In the last part we will present a short introduction to Cryptography, which studies mathematical techniques in order to secure the communication in presence of third parties.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is to present the basic topics of Coding Theory and Criptography.

AIMS AND LEARNING OUTCOMES

At the end of the course students will be able to:

- recognise the main classes of error correcting codes;
- master the main constructions of linear codes;
- recognise the principal decoding algorithms;
- master basic tools of modern cryptography and related algorithms.

PREREQUISITES

Necessary prerequisites are the following: vector spaces, groups, fields.

The courses "Algebra Lineare e Geometria Analitica" and "Algebra 2" are recommended.

TEACHING METHODS

Lectures and students' seminar.

EXAMS

EXAM DESCRIPTION

Oral exam.

ASSESSMENT METHODS

Questions of the oral exam will concern the main topics presented during the lectures. The aim is to establish not only whether students will have reached an appropriate level of knowledge, but also whether they can analize and approach problems related to Coding Theory and Cryptography.
