ABSTRACT:
In a communication network in which each of plural nodes (110 . . . 120) has an assigned node identifier, a node signature (step505) is generated by each node from an identifier of a component (e.g.,201) of the node or from statistical processing of information in the node. Each node distributes information data (300) that includes its assigned node identifier and its generated node signature (405). The node signatures in information data at a node having the same node identifier are compared (step710) to detect whether the node signatures for the same node identifier are different. The operation of the network is modified (e.g.,640, 725, 825or915) in response to detection of different node signatures for nodes having the same node identifier. The modification (725) may include removing all but one node of the nodes of the same node identifier detected as having different node signatures from network participation.
