FIELD: information technology.
SUBSTANCE: method for constructing crypto-code control structures and restoring the integrity of structured data arrays. In the method based on information accumulated in multidimensional data storage systems in form of p-dimensional structured data arrays, according to the rules of application ϕ-functions in time and space, displaying their elements through different types of transformations based on the use of hashing functions h and encoding f, into control symbols, crypto-code constructions are built, and in the event of possible degradation of the multidimensional data storage systems caused by the destructive effects of an attacker and disturbances in the functioning environment, fragmentation of the initial structured data arrays is performed, whereby the information contained in the resulting arrays continues to have a value sufficient for the user of the information system to make a decision.
EFFECT: possibility of monitoring and restoring the integrity of structured data arrays based on the use of cryptographic hash functions and error-correcting codes.
