Cryptography

Recommended Prerequisites

     BSc in Informatics Engineering or equivalent

Teaching Methods

Lecture classes (T): presentation and discussion around the topics of the course.

Lab classes (PL): application of theoretical concepts in projects.

The MSI theoretical classes will take place, preferably, Friday afternoon and Saturday morning. Theoretical classes will also be broadcast by teleconference and will be recorded to allow the students to follow the classes remotely.

The practical classes will be preferably booked Friday morning. The practical assignments may also be developed by the students in remote and asynchronous mode with remote support of teachers.

Learning Outcomes

This curicular unit aims to acquire knowledge about encryption algorithms. At the end of the course students should master basic cryptography and security mechanisms. It is also intended that the students acquire/develop the following core competencies:
-    Skills on cyber security assessment and management, security risk analysis, security risk assessment and management at organization and system level.
-    Practical application of the theoretical knowledge on security assessment and management, competences in analysis and synthesis, critical reasoning, and self-learning.

and the following secondary competencies:
-    Problem solving, oral and written communication, interpersonal relations, and team work.
