High school mathematics. Elementary knowledge of algebraic and combinatorial tasks. **Course Enrolment Limitations**- The course is also offered to the students of the fields other than those the course is directly associated with.
**fields of study / plans the course is directly associated with**- there are 53 fields of study the course is directly associated with, display
**Course objectives**- Tho goal of this course is to introduce the basics of theory of numbers with its applications to cryptography, and also the basics of coding and more advanced combinatorial methods.
**Learning outcomes**- At the end of this course, students should be able to: understand and use methods of number theory to solve simple tasks; understand approximately how results of number theory are applied in cryptography: understand basic computational context; model and solve simple combinatorial problems.
**Syllabus**- Number theory:
- divisiblity (gcd, extended Euclid algorithm, Bezout); numerics of big numbers (gcd, modular exponential); prime numbers (properties, basic theorems of arithmetics, factorization, prime number testing (Rabin-Miller, Mersenneho prime numbers); congruences (basic properties, small Fermat theorem; Euler theorem; linear congruences; binomial congruences a primitiv roots; discrete logarithm;
- Number theory applications:
- short introduction to asymetric cryptography (RSA, DH, ElGamal, DSA, ECC); basic coding theory (linear and polynomial codes);
- Combinatorics:
- reminder of basics of combinatorics; generalized binomial theorem; combinatorial identities; Catalan numbers; formal power series; (ordinary) generating functions; exponential generating functions; probabilistic generating functions; solving combinatorial problems with the help of generating functions; solving basic reccurences (Fibonacci).

**Teaching methods**- There are standard two-hour lectures and standard tutorial (in case of need replaced by ther distance form complemented by homework solving).
**Assessment methods**- During the semester, students will sit a mid-term exam, max 20 points. In the seminar groups there will be tests run, awarded in total max 20 points (13 tests per 2 points, the worst 3 results are erased; in case of the distance form, the tests will be replaced by homeworks). Out of these max 40 points, it is necessary to get at least 15 points in order to be allowed to sit the final exam in the exam period, consisting of a theoretical and a practical part, max 60 points. Altogether, it is possible to get max 100 points. For successful examination (the grade at least E) the student needs to obtain at least 50 points.
**Language of instruction**- Czech

The course is taught annually. **Listed among pre-requisites of other courses**
