Utroystvo FOR CRYPTOGRAPHIC DATA PROCESSING, cryptographic processing of data and programs

摘要

1. Device for cryptographic processing, comprising: a cryptographic processing unit configured to split the input components and the data bits to be processed in several lines and repeatedly performing data transformation operations applied to the data in the respective product lines using the round function, wherein that the cryptographic processing module has a structure designed for the input n / d-bit data obtained by dividing the n-bit data as Rin -period data according to the number d of the partition, to the appropriate line and repeatedly performing calculations as rounders computing, including data conversion operation using a round function, that module cryptographic processing performs the operation, during which the n / d-bit data in each line, having an output of round computations repeatedly divided into segments d / 2 data recombined again broken data segments to reconstruct d n / d-bit data other than the data output pa undovyh computing the previous stage, and setting the reconstructed data as input data for rounders calculations for the next stage, the round function includes F-function operation "XOR" between the output data or input data of F-functions on the one hand and the data in the other line with However, imodul cryptographic data sets of round computation result of the previous stage as an input to the next stage of round computing by performing satisfying
