| Outline of Final Research Achievements |
In this research, we realized dynamic diversifying methods in the Java platform by the novel mechanism instrumentation introduced in Java 5.
Our research consists of three categories; (A) hiding the program at the runtime, (B) reducing the overhead from the protection methods, and (C) evaluating the tolerance against dynamic analysis.
The outcomes of our research are: (A) the self-modification technique by methods folding, (B) lightweight and dynamic obfuscation method with invokedynamic instruction, and (C) the evaluation method for robustness of the protection methods by (C-1) Kolmogorov complexity, (C-2) stealthiness by perplexity, (C-3) identifying applied obfuscation methods towards de-obfuscation, and (C-4) birthmarking methods for more large scale software search.
