Приведены некоторые свойства тернарных (L, M)-квазигрупп, которые играют важную роль при анализе и проектировании криптографических схем на основе этих алгебр, такие как полиномиальная полнота, отсутствие нетривиальных конгруэнций.</p></abstract><trans-abstract xml:lang="en"><p>We construct an algorithm for transforming words using a set of ﬁnite quasigroups in an amount equal to the number of characters of the alphabet.
