The TSF gives a recipient evidence that identifies the originator of information so that the originator cannot later deny having sent it. Components: FCO_NRO.1 Selective proof of origin (evidence generated on request for specified information) and FCO_NRO.2 Enforced proof of origin (evidence always generated).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
