Abstract (en)
[origin: WO2016091574A1] An apparatus of a first node is provided for secure exchange of messages. A network authentication unit (902) is provided for performing an authentication procedure with a server to gain access to the mesh network, wherein the network authentication unit is configured to receive a network-wide key from the server. A peer authentication unit (903) is provided for performing an authentication procedure with a second node in the mesh network, wherein the peer authentication unit is configured to receive an identity of the second node through the mesh network, and to generate a pair-wise identity-based key between the first node and the second node, based on the pre-shared identity-based key material and the identity of the second node. A combined key generator (904) is provided for generating a combined key by combining the network-wide key with the pair-wise identity-based key.
