Learning outcomes
The aim of a course is to inform students about the basic cryptography tools and their usage during securing electronic information. Students will be acquainted with needs of information securing and with possibilities of cryptography tools. Lessons will be focused on the chosen parts of number theory, modular arithmetic, special mathematics functions, cipher systems, digital and electronic signature including management of pub-lic key of asymmetric encryption (a certificate of public key and activities of certificate authority). The basic principles of coding theory are explained as well.
Cryptography basic methods and use of these methods to security of electronic information.
Prerequisites
Basic course of higher mathematics
