SYSTEM OF ROBUST KEYS CONTROL AND METHOD OF ITS FUNCTIONING Russian patent published in 2009 - IPC H04L12/00 

FIELD: information technologies.

SUBSTANCE: system of robust keys control for servicing of network with cluster architecture uses trust center at the stage of key units generation and distribution, and distributed center of keys control for support of adequate functioning mode, provides level of secrecy and fault tolerance due to approved application of EKSYD and CuBES circuits, has guaranteed security in case of intercluster and intracluster interaction of units without participation of trust center and distributed center of keys control, in which trust center has executive processor circuit, generator of pseudo-random numbers, memory and transceiver; distributed center of keys control has executive processor circuit, generator of pseudo-random numbers, memory and transceiver, and every unit of network has executive processor circuit, memory and transceiver.

EFFECT: provision of high security and fault tolerance level, and also guaranteed security in case of intercluster and intracluster interaction of units without participation of trust center and distributed keys control center.
