Abstract: 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.

Abstract: The invention relates to a node (100) for a network such as a wireless control network or the like. In this network, each node (100) comprises a identifier (104) and keying material (102), means for authenticating (112) the node's identifier based on the node's keying material and means for checking (114) the access control rights of the node in a distributed manner based on the node's multidimensional identity and access rights corresponding to the node's identity. Additionally, the invention allows the node to generate a common key with any other node in the first keying first network that can be used to enable further material identifier secure communications.
