MATHEMATICAL MODEL AND ALGORITHM FOR DATA INTEGRITY CONTROL BASED ON THE RULES OF CODE CONSTRUCTION WITH UNEQUAL CHARACTER PROTECTION

Information and analytical systems are considered, the functioning of which is based on
the processing of multidimensional arrays of information in the conditions of destructive effects
of an attacker and environmental disturbances. A subsystem of data integrity control is proposed,
based on the use of redundant coding, in which the data to be protected is presented in the form
of blocks, pre-grouped according to the criterion of «information value» to ensure the correctness of
the user’s decision-making of an information and analytical system
