INTERNAL NETWORK FORMED BY NETWORK CRYPTOGRAPHIC PROTECTION MODULES Russian patent published in 2023 - IPC G06F21/60 H04L9/06 

FIELD: computer technology.

SUBSTANCE: invention is aimed at increasing the level of information security and security by highlighting the internal network within the existing open network. It is achieved due to the fact that (i-1) hardware-software complexes are introduced, to the external interfaces of each of which the corresponding modules of network cryptographic protection (NCP) are connected. Moreover, each of the (i-1) NCP is connected via an open network with a combined segment of the internal network through its NCP module. So, NCP modules are installed on the external interfaces of each hardware and software complex (HSC) that requires isolation from an open (general) network and is involved in the technological processes of processing information over the network and ensure that requests are passed through themselves only within the allowed communication model (protocols), with coding simplified in terms of resource or encryption with encapsulation of all internal HSC data traffic above the transport layer to other network elements.

EFFECT: increasing the level of information security and security by highlighting the internal network within the existing open network.
