METHOD FOR INTEGRITY CONTROL OF MULTIDIMENSIONAL DATA ARRAYS Russian patent published in 2022 - IPC G06F11/08 

FIELD: data arrays monitoring.

SUBSTANCE: invention relates to a method for monitoring the integrity of multidimensional data arrays. In the method for performing integrity control, data blocks Mi (i = 1, 2, …, n) are represented as fixed-length subblocks Mi,1, Mi,2, …, Mi,n, from which the reference hash codes Hi hash -functions h(Mi), the values of which are subsequently compared with the values of the hash codes of the hash function calculated from the checked data blocks in this case, a multidimensional data array of dimension k is represented as a 3-dimensional data array M[k, k, k], consisting of k3 data blocks Mi,j,r (r = j = r = 0, 1, …, k-1 ), which for integrity control will be placed in an array of dimensions k + 1, while filling from 0 to k-1 of its blocks, to which the hash function h is applied to detect signs of integrity violation, while the calculated hash codes Hi, j, r (i, j, r = 0, …, k) will be placed in 3k2 free blocks of the array and will be reference values, the values of which are compared with the values of the hash codes of the hash function calculated from the checked data blocks

EFFECT: ensuring data integrity control.
