Cryptography from NSU on Openedu

Everything related to cryptography and cryptanalysis was highly classified in the Soviet Union. That is why the achievements of Soviet cryptographers were published in secret journals available for Special services only. From that time we, Russian cryptographers, use in our work mathematical knowledge. In our course we present to you some intriguing and not too famous facts of Soviet and Russian cryptography. The key topics covered in the course "Cryptography: Boolean functions and related problems": * how cryptography developed in Russia and in the Soviet Union, including the facts which used to be top secret until very recent times; * Boolean functions and S-boxes, and how the resistance of a cipher depends on a cryptographic properties of a Boolean function; * methods of cryptanalysis; * some special and most intriguing types of cryptographic Boolean functions: bent functions and APN-functions (Almost Perfect Nonlinear Functions); * AI and ML for cryptography. Welcome to the course, and enjoy your learning! https://openedu.ru/course/nsu/CRYPTO/?session=2024_2025
