  The method of two-dimensional control and assurance of data integrity with
the possibility of their recovery for information systems operating under
conditions of random errors as well as errors generated through deliberate
actions of the attacker is proposed. The data recovery procedure is based on
the application of the mathematical apparatus of redundant residue number
system codes, and the control (verification of the recovered data validity
(reliability, accuracy)) of data integrity is performed by means of
cryptographic methods.
