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 tutorials (in case of need replaced by ther distance form).
**Assessment methods**- The attendance of the seminar groups will be monitored; in order to be allowed for the final exam, the maximum of 3 absences is allowed.

During the semester, students will sit two "mid-term" exams, probably in the time of the lectures, max 20 points (2 exams, 10 points each). Their contents will correspond to what will be covered by then in the seminar groups in the first/second half of the semester.

There will be given 13 homeworks per 2 points, mostly one homework each week, giving the gain of max 26 points from the homeworks.

Before the final exam, it is thus possible to get max 20 + 26 = 46 points, out of which at least 20 points will be needed in order to be allowed for the final exam.

The final exam will take place in the exam period and consists of a computational and a theoretical part (distributed roughly 70% : 30%), max 54 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
**Further comments (probably available only in Czech)**- Study Materials

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