METHOD OF ENSURING THE INTEGRITY OF DATA Russian patent published in 2019 - IPC G06F11/08 H04L9/32 

FIELD: information technology.

SUBSTANCE: invention relates to a method for ensuring data integrity. Method consists in the fact that the detection and localization of an error in the records m₁, m₂, …, m_n data block M is provided by a system of hash codes by calculating the hash function signatures, moreover, the hash code system provides for records m₁, m₂, …, m_n, which are an information group of n records designed to uniquely restore the integrity of the data block M, calculating the control group of k-n records m_n+1, …, m_k, additionally entered to correct the error arising under the conditions of deliberate actions of the attacker, in the event of which the restoration of the integrity of the data block M is carried out by reconfiguring the system by eliminating one or several records, where i=1, 2, …, k, with an error that has occurred, error detection and verification of data integrity recovery is performed by comparing the calculated signature S of the hash function h(M) from the checked data block M with the previously calculated signature S* hash function h(M*) from the original block data M*.

EFFECT: ensuring the integrity of the data and the restoration of the integrity of the data with their possible change in the conditions of the deliberate effects of the attacker.
