摘　　要：针对PE文件存在水印鲁棒性差和数据率低的不足,本文基于混沌扰动对子水印信息加密,提高了水印的鲁棒性;基于混沌散列把水印信息分散编码到整个代码段中,提高了水印的隐蔽性;应用MPPCT_DF动态图结构,增加图节点编码量,同时每个节点增加一个静态数据域,扩大了信息存储量。基于此,提出一种混沌加载PE文件的动态图水印(CBDW_PE)技术方案,并给出主要组成模块、关键算法,展示系统实现及概念数据模型,最后对算法进行对比和分析。经比较,该技术对剪切、篡改和逆向攻击等具有较好的效果,提高了水印的安全性与隐蔽性,有效改善了PE文件数据率低的问题,便于有意义水印的加载。In view of the deficiencies of poor watermark robustness and low data rate in PE files,this paper encrypts the sub-watermark information based on chaotic perturbation,which improves the robustness of the watermark;disperses and encodes the watermark information into the whole code segment based on chaotic hashing,which improves the hiddenness of the watermark;and applies the dynamic graph structure of MPPCT_DF,which increases the amount of the node encoding of the graph,and at the same time,increases a static data field in each node,which enlarges the information storage capacity.Based on this,a chaotic loading PE file dynamic graph watermarking(CBDW_PE)technology scheme is proposed,and gives the main component modules,key algorithms,shows the system implementation and conceptual data model,and finally compares and analyzes the algorithms.After comparison,the technology has better effect on shearing,tampering and reverse attack,improves the security and concealment of watermark,effectively improves the problem of low data rate of PE files,and facilitates the loading of meaningful watermark.
