摘　　要：根据PE文件中指令的信息冗余及PE文件的特点,提出了一种新的基于指令长度编码的PE软件水印方法。该方法使用SMC技术和指令的长度来编码水印,建立了水印和软件的依赖。实验结果表明,此方法能够以适中的性能代价来建立这种依赖并以此提高了水印抵抗多种攻击的能力。According to the information redundance in the instructions and the characteristics of the PE file, a new PE software watermarking encoded based on length ofinstructions method is proposed. The advantage of this method is that a dependence relation between software and watermark is constructed by using the SMC technology and the length of instructions to encode watermark. Experimental result indicates that the resistance of the watermark to a variety of attacks is improved by constructing the dependence relation at modest cost.
