Interval-based network flow watermarking scheme based on local inversion number modulation
摘要
Abstract
With the widespread use of encrypted communications and anonymous networks,cybersecurity threats have become increasingly complex,and network flow watermarking has emerged as an important technical means for tracing malicious cyberattacks.However,existing network flow watermarking methods still suffer from syn-chronization difficulties and insufficient robustness in complex network environments.To address these issues,an interval-based network flow watermarking scheme based on local inversion number modulation was proposed.Firstly,a synchronization header structure integrating a long interval feature and a fixed local packet-order feature was designed,and a corresponding extraction and decision mechanism was constructed to establish a consistent temporal reference between the embedder and the detector,thereby enabling accurate localization of the watermark starting position.Secondly the watermark embedding interval length was adaptively determined according to the statistical characteristics of the target traffic.The traffic flow was divided into a number of consecutive intervals,each of which was further divided into two subintervals,namely the front and rear subintervals.Finally,the corre-sponding subinterval was selected according to the watermark bit to be embedded,and watermark bits were embed-ded by reordering packets within a local window of the selected subinterval under inversion number constraints.Ex-perimental results show that the proposed synchronization header achieves good detection performance under both packet loss and packet reordering interference,while packet reordering has a relatively limited impact on synchroni-zation header detection.Compared with existing representative methods,the proposed scheme demonstrates supe-rior robustness and detection performance under typical network interference conditions.关键词
