Anotace:

Students understand the mathematical fundamentals of cryptography and have an overview of current cryptographic algorithms and applications: symmetric and asymmetric cryptosystems, and hash functions. They also learn the fundamentals of secure programming and IT security, the fundamentals of designing and using modern cryptosystems for computer systems. They are able to properly and securely use cryptographic primitives and systems that are based on these primitives. Students are introduced to legal aspects of information security, security standards, social engineering, and basic principles of security management.

Cíle studia:

The module provides the fundamental theoretical knowledge and practical skills concerning cryptographic systems and their use. Students will understand the principles of basic crypto algorithms and the basics of secure programming and IT security. A key point is the understanding of the concept of security in the context of mathematical principles of cryptographic primitives, as well as their use in complex systems. In the labs, students gain practical skills in using standard cryptographic methods with emphasis on security and learn elementary cryptanalysis methods. Students are also introduced to the basic rules of security management, security standards and legal aspects of security.
