Rezumat

In this paper it proposed a fast method for calculating of the subsets column of partial derivatives of Boolean functions, in base of which can be used to generate the encryption keys. To determine the indicated subsets are used blocks of partitions, built on some variable of Boolean function. Is determined optimal coverage with these blocks for subset of column of this function. Indicated cover allows to significantly reduce of computation time derivatives and in result enables rapid change of encryption keys.
