ABSTRACT. The description of a new encryption key generation algorithm based on non-linear transformations of matrix structures in the form of Sudoku grids presented. The implementation of such a method for constructing cryptographic primitives in the work of the HiSNeC block encoder is considered. With standard NIST STS tests, we analyzed the statistical properties of cipher-text code sequences generated by the encoder in the mode of dynamically changing input keys. The test results is confirmed the high cryptographic strength of the encoder. This allows us to recommend the HiSNeC encoder for use in low-resource cryptographic protection systems.
