• Deepening the theoretical knowledge of the subject "Applied cryptology."
• Knowledge of design techniques of symmetric and asymmetric ciphers.
• Acquisition of experience in designing symmetric block algorithms with the help of subject programming language Cryptol.

• Probability theory.
• Basics of discrete mathematics.
• Cryptographic systems and protocols.
• Applied cryptology.

Course work is the design of symmetric and asymmetric ciphers, analyzing their sustainability. The objective of the course is to develop a symmetric block cipher algorithm based on Feistel cipher or permutation substitution structures, their modeling and analysis by Cryptol. Also considered as tasks implement asymmetric system.
