Proposed  application of cubic fractal changes to the encryption and decryption, grayscale color using elements of the RSA algorithm.

The paper contains the results of investigation of statistical features based on dispersion and their comparison in conditions of using for metal surface classification. The partitioning of whole set of characteristic values into ranges, which correspond to separate types of metal alloys, is used for classification.

An application of the kvaternarn fractional-linear form with using the standard elements of the RSA algorithm for encryption and decryption of two-dimensional images is resistant to unauthorized access to images clearly distinguished contours.
