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

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to methods of providing secure communication in a network. The method comprises: an administration device provided with root keying materials, and steps of: generating, by the administration device based on the root keying materials, parts of keying material of a first node containing a certain number of sub-elements, and parts of keying material of the first node, assembled for generating a first terminated key, the administration device selects a subset of sub-elements of the first parts of the keying material, wherein the number of selected sub-elements is less than or equal to the total number of sub-elements of the first parts of the keying material, and the selected sub-elements form partial parts of the keying material of the first node or a symmetrical key generation mechanism, the first node generates, based on the symmetrical key generation mechanism of the first node and on a second node identifier, a first key used to provide secure communication with a second node.

EFFECT: more secure data transmission in a network.
