FIELD: information technology.
SUBSTANCE: network is provided with a new node (106) comprising node specific cryptographic key material, wherein the new node is configured to specify a cryptographic key based on the node specific cryptographic key material, a first node (102) requiring the cryptographic key for network security initialisation and means (108) for providing a missing cryptographic key to the first node from a storage different from the new node, wherein the missing cryptographic key is equal to the cryptographic key.
EFFECT: providing safe initialisation of network cryptographic keys.
