Anotation:

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.
