面向流量测试的网络流水印标记和溯源模型
Abstract: In order to label and trace the provenance of any network simulation flow in network testbed, an interval-based flow watermarking and provenance tracing model was proposed. When a simulation flow was generated, this model first transformed the user’s watermarking content into 0-1 bit sequence and then sent packets of the flow at particular intervals according to the 0-1 bit sequence to label the flow. When the simulation flow was captured by the model, the time intervals between packets in the flow were 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.
