iiiiiii200402.tex摘要为了有效地检测Java类文件的盗窃，我们提出了Java胎记的概念。由于胎记是每个类文件的唯一和原生特征，因此具有相同胎记的类文件很容易被怀疑为副本。然而，胎记对复杂攻击的性能和耐受性还没有得到很好的评估。为了澄清这些问题，本文进行了两个实验。在第一个实验中，我们证明，建议的胎记成功区分非复制文件在实际的Java应用程序（97.8005%）。第二个实验表明，提出的胎记是相当宽容的攻击与自动程序优化器/混淆器（93.3876%）。摘要为了有效地检测Java类文件的盗窃，我们提出了Java胎记的概念。由于胎记是每个类文件的唯一和原生特征，因此具有相同胎记的类文件很容易被怀疑为副本。然而，胎记对复杂攻击的性能和耐受性还没有得到很好的评估。为了澄清这些问题，本文进行了两个实验。在第一个实验中，我们证明，建议的胎记成功区分非复制文件在实际的Java应用程序（97.8005%）。第二个实验表明，提出的胎记是相当宽容的攻击与自动程序优化器/混淆器（93.3876%）。??????? 1.7
iiiiiii 200402.tex ABSTRACT To detect theft of Java class files efficiently, we have so far proposed a concept of Java birthmarks. Since the birthmarks are unique and native characteristics of every class file, a class file with the same birthmark of another can be easily suspected as a copy. However, performance and tolerance of the birthmarks against sophisticated attacks had not been evaluated well. To clarify these issues, this paper conducts two experiments. In the first experiment, we demonstrate that the proposed birthmarks successfully distinguish non-copied files in practical Java application (97.8005%). The second experiment shows that the proposed birthmarks are quite tolerant of attacks with automatic program optimizers/obfuscators (93.3876%). ======= ABSTRACT To detect theft of Java class files efficiently, we have so far proposed a concept of Java birthmarks.
