METHOD FOR INTEGRITY CONTROL OF MULTIDIMENSIONAL DATA ARRAYS BASED ON THE RULES OF CONSTRUCTION OF TRIANGULAR CODES Russian patent published in 2022 - IPC G06F11/08 

FIELD: data arrays controlling.

SUBSTANCE: invention relates to a method for controlling the integrity of multidimensional data arrays based on the rules for constructing cubic codes. In the method, detection and localization of a data block Mi (i = 1, 2, …, k) with signs of integrity violation is carried out by calculating a system of hash codes formed from hash codes calculated from a set of k data blocks M1, M2, …, Mk , and comparing its values ​​with the values ​​of the reference system of hash codes, while the data blocks Mi,j,r (i = j = r = 0, 1, …, k-1) are located in a cube of size k3, to which three sides are added reference hash codes Hk,j,r, Hi,k,r, Hi,j,k, (i = j = r = 0, 1, …, k-1), which are calculated from a set of k3 data blocks Mi,j,r located in the cube, while to control the integrity of the reference hash codes Hk,j,r, Hi,k,r, Hi,j,k, the hash codes Hk,k ,r, Hk,j,k, Hi,k,k, the values ​​of which are compared with the values ​​of the hash codes H'k,k,r, H'k,j,k, H'i,k,k, calculated upon request to the use of data subject to protection.

EFFECT: ensuring data integrity control.
