STUDY OF METHODS FOR ENSURING INFORMATION INTEGRITY IN INFORMATION SYSTEMS WITH OPTICAL COMMUNICATION CHANNELS

The relevance of the work lies in the fact that the number of information systems with optical communication channels is increasing. However, for such systems, the optimal method for ensuring the integrity of information has not been identified. The purpose of the work is to identify the best method for ensuring the integrity of information in information systems with optical communication channels. This article discusses methods for ensuring the integrity of information at the stages of storage and transmission of information. The main method for ensuring the integrity of information at the storage stage is the data backup method. Parallel information transfer is the main method at the stage of information transfer. As a result of the study, the following conclusion was made: to ensure maximum security of information integrity, it is necessary to apply an integrated approach and use immediately both data backup and protection methods at the stage of information transfer.
