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。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 infor- mation 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 divid- ing 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.
