METHOD FOR ISOLATING DATA PACKETS TRANSMITTED OVER PUBLIC NETWORKS IN THE TCP/IP FAMILY PROTOCOL FORMAT USING A COMBINATION OF MASKING, ENCRYPTION AND CONTROL METHODS FOR THE RECEIVED DATA

摘要

FIELD: information protection. ;SUBSTANCE: invention relates to the field of digital information transmission. A data packet isolation module is proposed, which is made with the possibility of embedding between the network adapter and the channel layer protocol module for processing data packets. The module performs the transformation of data packets, in particular, determining the connection identifier for the recipient of the processed data packet; calculation of the offset relative to the beginning of the processed data packet and the size of the source data for compression and/or encryption; creation of a copy of the source packet with its addition with data areas that ensure its further processing; initialization and filling in the structure of the accompanying data for the processed data packet. Data is transmitted from the sender to the recipient via standard network routing devices in public networks and/or in local networks, while the transmitted data contains data packets converted by means of a data packet isolation module. ;EFFECT: increase in the security of data exchange in the data transmission network. ;16 cl, 3 dwg, 11 tbl
