摘要

物件導向語言Java已是非常流行的程式語言，但它的類別檔（class file）中含有大量的程式資訊，因而容易被逆編譯（de-compile）。本論文提出一套程式碼混亂器。它以去除動態繫結（dynamic binding）為手段來進行混亂化（obfuscation），使混亂後的程式碼更不容易被研讀，也使智慧財產能得到更好的保護。

並列摘要

Java, the object-oriented language, is a very popular programming language. But its class file, containing vast code information, is easy to be de-compiled. An obfuscation tool based on removing dynamic binding is proposed in this paper. After the obfuscation, code is more difficult to be studied, and the intellectual property will be protected in a better manner.
