The goal is to make students familiar with the basic concepts applied cryptography, including classical cryptography and modern secret key and public key cryptography.
Students will learn basic principles of applied cryptography, including classical cryptography and modern secret key and public key cryptography.
Students will learn the role of security and functionality in information systems.

This course is essential to all engineers working in the areas of computer engineering. Students will learn basic principles of information systems security and cryptography.

A mid-term exam evaluation and an evaluation of projects.
A written mid-term test, a regular evaluation of projects. The test does not have correction option, the final exam has two possible correction terms.

To obtain at least one point in each project.
