摘　　要：混淆技术被认为是当前最有效的软件保护方法之一,混淆编译是一项新的混淆技术应用框架,该方法将程序的编译混淆而不是原有的混淆程序本身,这种被混淆的编译可以较好地隐藏程序功能,从而达到软件保护的目的。另外,软件水印技术也是软件保护的重要途径,但水印算法鲁棒性普遍较差,如果将混淆技术与水印结合,利用混淆在保护软件的同时保证水印的鲁棒性,那么软件系统的安全性会更强。利用一个实例进行初步讨论。Software protection via obscurity is now considered one of most effective for securing software systems. A new framework for obfuscating the program interpretation instead of obfuscating the program itself is introduced. The obfuscated interpretation enables us to hide functionality of a given program P. Also software watermarking is a important approach in software protection, but the robust is always unsatisfactory, Connecting watermarks with obfuscation is proposed, so the robust is improved. The protection is better than single technology. This possibility in a sample is discussed.
