The Application Research of Characteristic Code Techniques in Attack and Defense

In order to explore the development trends of viruses attack-defense tactics, diversified characteristic code techniques are deeply discussed in this paper. By experiments of manually locating, analyzing and verifying the mechanism of three techniques, single characteristic code, multiple characteristic code and composite characteristic code, have been expounded profoundly and compared distinctly. Then several technological means, such as alteration, packing and encryption are used for viruses to escape from being detected and killed. However, the effect of simply using one characteristic code technique remains a doubt, once the single characteristic code technique is joined with proactive protection, greater breakthrough can be archived in attack-defense counter.
