Course detail

The objective of this subject is to provide fundamental theoretical knowledge of and practical skills in data protection and data security in modern communication and information systems.

Students will be introduced to applications of cryptographic mechanisms in communications and networks. They will learn the basic principles of information system security. They will also learn applied cryptography, including classical cryptography and modern secret key and public key cryptography.

The subject knowledge on the Bachelor´s degree level is requested.
