基于迷乱变换的动态路径水印实现方案

结合软件水印技术的最新研究成果，提出了一种基于迷乱变换的动态路径水印实现方案。该方案充分利用动态图别名分析难的特点为不透明分支的构造创造条件，通过构造低开销、高隐蔽性和高鲁棒性的不透明分支对程序实施控制流迷乱变换，并将水印数据嵌入迷乱变换后程序的特定执行轨迹中。分析了该方案在隐藏信息量、隐蔽性和鲁棒性等方面的性能。

Dynamic Path-based Watermark Scheme Based on Obfuscated Transformation

Based on the latest research achievements of software watermark technology, this paper presents a new dynamic path-based watermark scheme which is based on obfuscated transformations. The scheme utilizes the property, called as the difficulty of alias analysis on dynamic graphs, to create relevant conditions for the conformation of opaque predications, performs control flow obfuscated transformations to a program by manufacturing cheap, secrete and robust opaque constructs, and embeds the watermark data into the specific executed tracks of the obfuscated program. It analyzes the performance of the scheme from aspects such as data rate, secxecy and robustness.
