Year	1
Semester	S2
ECTS Credits	6
Workload	PL(30H)/T(30H)
Scientific area	Informatics
Entry requirements	Knowledge of programming, mathematics and statistics.
Learning outcomes	The objectives of this UC are to introduce the concepts and mechanisms for Information Security and develop the ideas more profoundly. The UC aims to give the student a solid theoretical and practical foundation about modern cryptography. The UC aims to expose the student to the advanced concepts of modern cryptography studying modern crypt primitives and security protocols focusing on information security. Other aims are to study vulnerabilities in crypto primitives and protocols using formal analyse and modelling.
