中文摘要: 针对流交换中网络抖动和流变换导致的流指纹不可用、不可信问题，提出一种防篡改且可恢复的流指纹编码方案。通过提出流特征信息作为自适应参数，以此作为超混沌系统的初值，构造双重指纹。与此同时，利用门限理论，以提高流指纹信息的防篡改能力和流指纹的自恢复能力。通过增加密钥空间以加大攻击难度、降低检测计算复杂度以提高检测效率。同时，为了实现流指纹的自恢复能力，将流指纹分为相互关联的两重子指纹信息，并对每一重子指纹再次进行分散。此外，对该方案的防篡改性和可自恢复能力进行了理论分析。最后，实验说明了该方案的高准确率和良好实用性。
Abstract: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.
