Abstract
The article deals with the Automated Systems (AS) operating under the destructive influences of an attacker and disturbances of the operating environment with a continuous increase in the amount of information accumulated in data storage systems (DSS) used in their interests. When compensating for the effects of an attacker and disturbances in the operating environment, the use of storage is complicated by the increased control information which entered for protection. At the same time, the amount of introduced redundancy is increasing in direct proportion to the increasing volume of information accumulated in the storage. For such operating conditions, one of the most important tasks is the organization of secure data storage with restrictions on allowable resource costs. A subsystem of data integrity control based on the cryptographic methods, in particular hash functions, is proposed. The hash function used in the developed subsystem is based on the rules of construction of the Reed-Solomon code, which makes it possible to detect and localize data arrays with signs of integrity violations without calculating and introducing a high redundancy of control information for this.
