Abstract


With the development of computer technology , especially the development of the computer network , the malicious code is also in constant development . The number of malicious code has exponential growth than in the past . Traditional malicious code is the basic form of the virus , and the current variety of forms of malicious code , such as worms , viruses , Trojan horses, and malicious plug . Functional analysis , the general functions of traditional malicious code single most data destruction , malicious code also has data theft , tampering and other functions , and the use of a large number of anti-debugging , anti- tracking , anti- detection technology to protect itself . Evidently, the dangers of malicious code on the computer development has become increasingly significant , but also to detect more and more difficult . Traditional anti-virus software is only used in the detection of malicious code , binary feature code matching techniques to detect . Since this method must be binary feature code of the malicious code , once the malicious code encryption changed its binary feature code , the method will be completely ineffective . The traditional anti-virus software in the face of this malicious code has appeared to be inadequate . On the basis of the basic theory and key technology of this paper expounded the mode matching algorithm , heuristic scanning algorithm , as well as virtual machine technology , lack of malicious code detection engine pattern matching algorithm proposed to improve the program . In addition , the characteristic behavior of the engine based on heuristic scanning algorithms and virtual machine technology , the paper established a combination of binary feature matching , match the behavioral characteristics as well as cloud detection of new malicious code detection method prototype system . The results of this research can effectively improve the system resources and make full use of network resources , and to resist the invasion of malicious code , the maintenance of a healthy environment of the Internet , and then create a harmonious network society has a positive significance .
