Malicious code recognition method based on cloud computing

Abstract

The invention discloses a malicious code recognition method based on cloud computing. The technical problems needed to be solved includes: firstly, variation of current malicious codes is quickened, encryption keys are changed continuously to enable generated code bodies to be extremely low in similarity by the aid of an encryption mechanism of the malicious codes, and traditional detection engines based on feature codes cannot recognize the malicious codes, so that searching and killing rate decreases continuously; and secondly, with development of technology, more self-protection technologies are added into the malicious codes and especially withstand currently popular virtual machine searching and killing mechanisms, and the analysis process of codes which are quite simple in the real environment is extremely complex in virtual machines of antivirus engines, so that the malicious codes are finally unrecognized. Obviously, new feasible schemes are needed to solve the problem of malicious code recognition in the current environment so as to defend effectively.

Description

technical field [0001] The present invention is a solution for identifying malicious codes based on a cloud computing platform, which mainly solves the problems that current malicious codes mutate more and more quickly, and traditional virus database updates cannot achieve timely detection and killing, and belongs to the field of virus detection and protection. Background technique [0002] With the development of computer technology, especially the rapid development of computer networks, the number of malicious codes has an exponential growth trend. Early malicious codes did not adopt too many self-protection mechanisms, and all had fixed signatures. Therefore, anti-virus software can easily detect virus programs hidden in the system by using virus signature matching. However, with the development of technology, malicious codes have adopted self-protection techniques against anti-virus detection engines. As a result, the accuracy of traditional signature-based antivirus e...
