Abstract: Examples for identification and authentication of hardware. Techniques may include receiving a node identifier during an initial phase of the node. The node identifier may include an initial unique identifier of the node. The node may receive a latest change identifier during a phase change of the node, wherein the phase change may cause a hierarchical change of the node. The latest change identifier is configured to incorporate a latest unique identifier corresponding to a latest system and one or more unique identifiers corresponding to one or more earlier systems of the node. Further, responsive to the reception of the latest change identifier, delete an earlier change identifier, and the node may send the second change identifier to a management service, in response to a request for authentication of the node by the management service.
