METHOD AND APPARATUS FOR CONTROLLING DATA STREAMS OF A DISTRIBUTED INFORMATION SYSTEM USING IDENTIFIERS Russian patent published in 2019 - IPC H04L9/32 

FIELD: information technology.

SUBSTANCE: invention relates to information security. Method of controlling data flows consists in the fact that distributed information system uses identifiers of authorized data streams by generating them by cryptographic transformation and checking on analysis units. When generating a transmitted data stream on a specific network node, a current identifier I_cur, for which cryptographic transformation is used, then recorded in IP packet of transmitted data stream formed current identifier I_cur, response identifier I_res is generated, for which cryptographic transformation is used in reverse order. After receiving the data stream, a response identifier I_res and comparing obtained values with previously stored current identifier I_cur, correcting the switching table in case of mismatch values separated from the response and current identifiers, then, using new parameters of network interaction, blocking this data stream, and if match continues its transfer.

EFFECT: technical result is wider range of means.
