METHOD FOR INTEGRITY CONTROL OF MULTIDIMENSIONAL DATA ARRAYS BASED ON RECTANGULAR CODE CONSTRUCTION RULES 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 rectangular codes. In the method for detection and localization of a data block Mi (i = 0, 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, М₂, …, M_k, and comparing its values ​​with the values ​​of the reference system of hash codes, while data blocks Mi,j (i = 0, 1, …, n-1; j = 0, 1, …, k-1) are located in a rectangle of size n on k, to each row and column of which reference hash codes H_i,k, H_n,j are added (i = 0, 1, …, n-1; j = 0, 1, …, k-1), which are calculated from a set of n⋅k data blocks M_i,j located in the corresponding rows and columns of the rectangle, while to control the integrity of the reference hash codes H_i,k, H_n,j the hash code H_n,k is calculated, the value of which is compared with the value hash code Н'_n,k, calculated when requesting the use of data to be protected.

EFFECT: ensuring data integrity control.
