Beschreibung
Zusammenfassung:	The invention relates to the field of computer engineering and cryptography and, in particular, to methods for implementing linear transformations which operate with a specified speed and require minimum amount of memory, for further usage in devices for cryptographic protection of data. The technical result relates to enabling to select inter-related parameters (performance and required amount of memory) for a particular computing system when implementing a high-dimensional linear transformation. The use of the present method allows to reduce the amount of consumed memory at a given word size of processors employed. To this end, based on a specified linear transformation, a modified linear shift register of Galois-type or Fibonacci-type is generated according to the rules provided in the disclosed method, and the usage thereof enables to obtain the indicated technical result.
