Aimed at problems of unavailable and unreliable of net-flow fingerprint caused by net-flow transformation problems and network jitter,tamper proof and recoverable net-flow fingerprint coding scheme was proposed.The processed net-flow characteristic information was proposed as adaptive parameters and used as initial of hyper-chaos system.Based on that,dual fingerprint was made.The threshold theory was used to improve the tamper-proofing capability the self-recovery ability of net-flow fingerprint information.By dividing the net-flow fingerprint into two interrelated sub-fingerprint,the self-recovery ability of net-flow fingerprint was improved.What’s more,the capability of tamper proofing and self-restoration capability of tamper-proof and recoverable net-flow fingerprint coding scheme was analyzed.Finally,the availability and correctness of this scheme was verified by experiments.
