A system-on-chip (SoC) method and apparatus are disclosed for checking end-to-end integrity of communications over an network interconnect, where the SoC includes an initiator subsystem connected over the network interconnect to a target subsystem, wherein a first integrity module is configured to compute a first integrity value based on regular transaction messages sent or received by the initiator subsystem and to send a protecting information transaction (PIT) message over the network interconnect to the target subsystem, wherein a second integrity module is configured to compute a second integrity value based on regular transaction messages sent or received by the destination subsystem and to send a PIT response message over the network interconnect to the initiator subsystem, and wherein a compatibility module compares the first and second integrity values to verify the end-to-end integrity of the regular transaction messages sent or received over the network interconnect.
