METHOD FOR CONTROLLING DATA INTEGRITY BASED ON THE RULES FOR CONSTRUCTION OF CRYPTOGRAPHIC FRACTAL Russian patent published in 2023 - IPC G06F21/64 H04L9/40 

FIELD: storage systems.

SUBSTANCE: methods for monitoring data integrity in storage systems. The technical result is achieved by fragmenting the M data block into M⁽¹⁾, M⁽²⁾, M⁽³⁾ data blocks of a fixed length, each of which, in turn, is also fragmented into data blocks, to which the h hash function is applied to control integrity, and the hashing scheme is based on the rules for constructing Pascal’s triangle and is presented in the form of a triangular-shaped table, obtained for data blocks M ^(ϕ), the schemes for applying the h hash function are combined into a common scheme, which is intermediate and the M data block to be protected is designated as M^(I), when constructing two other schemes according to the same rules for other M^(II), M^(III) data blocks and combining them in the order presented for the M data block, the resulting data integrity control scheme is a scheme based on the rules for constructing a cryptographic fractal.

EFFECT: ensuring data integrity control without introducing additional control information.
