Abstract:
The present invention relates to a method for secure communications and communication networks having communication devices, using secure means like encryption system for securing communications. More particularly, the present invention relates to a method for secure communications 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 keying root shares formed by keying root share segments. The method using key segmentation for pre-distributing keying material according to a variable distribution for increasing the resiliency of existing methods.
