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

FIELD: computer science.

SUBSTANCE: invention relates to a method for controlling the integrity of multidimensional data arrays based on the rules for constructing square codes. In the method, the 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 the set of k data blocks M1, M2, …, Mk , and comparing its values with the values of the reference system of hash codes, while data blocks Mi,j (i = j = 0,1, …, k-1) are located in a square of size k2, reference hash codes Hi,k Hk,j (i = j = 0.1, …,, k-1) are added to each row and column of which are calculated from the set of k2 data blocks Mi,j located in the corresponding rows and columns square, while to control the integrity of the reference hash codes Hi,k Hk,j, the hash code Hk,k is calculated, the value of which is compared with the value of the hash code calculated when requesting the use of data to be protected.

EFFECT: ensuring data integrity control.
