Abstract
According to an aspect of the invention, a method for establishing secure communication between nodes in a network is conceived, wherein the network comprises a key manager which accommodates a key-manager-specific public key and a corresponding key-manager-specific private key; wherein a copy of the key-manager-specific public key is stored in an installation device; wherein the installation device provides a new node with the copy of the key-manager-specific public key; and wherein said new node is registered with the key manager by providing a node-specific public key and an identifier of said new node to the key manager, such that other nodes in the network may setup end-to-end secure connections with said new node by requesting the node-specific public key of said new node from the key manager.
