In order to label and trace the provenance of any simulated flowin multi-tenant network testbed,an interval-based flowwatermarking and provenance tracing model was proposed. When a simulation flowwas generated,this model first transformed the user's watermarking content into 0-1 bit sequence and then sent packets of the flowat particular intervals according to the 0-1 bit sequence to label the flow. When the simulation flowwas captured by the model,the time intervals between packets in the flowwere transformed into the 0-1 bit sequence so that the watermarking content could be extracted to trace the provenance of this simulation flow. The resilience against various known attack techniques is illustrated through theoretical analysis. Moreover,a large number of experiments prove the validity of this model in tracing simulation flows under both normal and abnormal circumstance.
