Camouflage Technique Of Code Based On Binarycode Equivalence Substiution

Development of Internet Security' Technology includes two aspects as technology of Internet Attack and technology of Internet Protect,as one of the most important aspect in Internet Attack Technology,technology of code disguise is used to enforce ability of anti-detecting for special code,then realize the function to protect and hide sensitive code in internet information fight.This paper mainly researches code disguise technology in order to develop some tools for code equivalent exchange which can resist statistic detecting.From the point of researching code disguise,this paper summarizes the investigating status of code detecting technology,compares all kinds of dynamic or static analysis and detecting technology,mainly analyses code detecting technology based on static character code,and researches all kinds of anti-detecting methods based on source code and binary code,then introduces exchange technology to code disguise,brings forward a code disguise method based on binary code equivalent exchange. On windows platform,I have designed and realized a suit of code disguise tools based on binary code equivalenct exchange technology,and achieve the aim to program metamorphose by modify the character code in target program and software anti-detecting to prolong its existing cycle.Lastly,this paper give the test results of all realized tools,results show that the suit of code disguise tools based on binary code equivalenct transform can metamorphose some special softwares effectively and make them take on benign anyi-detecting ability.
