METHOD FOR SECURE COMMUNICATION IN NETWORK, COMMUNICATION DEVICE, NETWORK AND COMPUTER PROGRAMME THEREFOR Russian patent published in 2014 - IPC H04L9/08 G06F21/62 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering and specifically to means of secure communication in a network. The method relates to secure transmission of information from a first node (N1) to a second node (N2) in a network, the first node comprising a first node keying material (KM(ID1)), the second node comprising a second node keying material (KM(ID2)), wherein the keying materials of the first node and of the second node comprise each a plurality of shared keying root parts formed by segments of the shared keying root parts. A communication network, having at least two communication devices, carries out said method.

EFFECT: safer communication by dividing keys into segments for predistributed keying material according to a variable distribution.
