چکیده
Дано решение открытой проблемы олимпиады по криптографии NSUCRYPTO-2018: показано, что не существует ортогональных массивов OA (16L, 11, 2, 4) с L = 6 и 7. Этот результат позволяет определить минимальные веса некоторых корреляционно-иммунных булевых функций высокого порядка.

Nonexistence of certain binary orthogonal arrays
We prove that binary orthogonal arrays of strength 8, length 12 and cardinality 1536 do not exist. This implies the nonexistence of arrays of parameters (strength,length,cardinality) = (n, n + 4, 6.2) for every integer n ≥ 8.

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Nonexistence of a few binary orthogonal arrays
We develop and apply combinatorial algorithms for investigation of the feasible distance distributions of binary orthogonal arrays with respect to a point of the ambient binary Hamming space utilizing constraints imposed from the relations between the distance distributions of connected arrays. This turns out to be strong enough and we prove the nonexistence of binary orthogonal arrays of param...
