NETWORK AND METHOD FOR ESTABLISHING A SECURE NETWORK

摘要

The invention relates to a network with a first node (102) comprising first pre-distributed keying material being assigned to the first node before the first node is connected to the network and a second node (104) comprising second pre- distributed keying material being assigned to the second node before the second node is connected to the network. The first node is configured to establish a secure communication (112) to the second node based on the first and second pre-distributed keying materials, without relying on a trust center (108). Pre-distributed keying materials can be replaced in a secure manner with post-deployed keying materials by the network trust center. Nodes can establish further secure communications based on post-deployed keying materials.
