Cryptography and Information Security - B6B32KAB

Main course
Student survey results
Credits 5
Semesters Winter
Completion Assessment + Examination
Language of teaching undefined
Extent of teaching 2P + 2L + 2D
Annotation
The Information Security course provides a complete source of information on the field of security of information systems and information technologies. The most of information in today society is created, transferred, stored in electronic form so information security is very important part of it. Technical background for information security is provided by cryptology.
Study targets

Communications Security - B4M36KBE

Student survey results
Credits 6
Semesters Summer
Completion Assessment + Examination
Language of teaching Czech
Extent of teaching 3P+2C
Annotation
The course provides a complete source of information on the field of security of information systems and information technologies. The most of information in today's world is created, transferred, stored in electronic form so information security is very important part of it. On successful completion of this course, students should be able to define the cryptographic primitives symmetric / asymmetric encryption, digital signatures, cryptographic hash function, and message authentication codes. They should be able to explain the security features offered by the latest versions of the most important security protocols operating on the TCP/IP stack (IPsec, TLS, SSH, PGP) and describe known attacks against these security protocols.
Study targets
The students should be able to select and apply the appropriate cryptographic primitives in different application scenarios. They should be able to select the appropriate security protocols in a given scenario and configure the appropriate options for the selection of the appropriate cryptographic building blocks applied within the studied protocols.
