Abstract

Abstract:

Aiming at the defects of virtual machine antivirus technologies, a hiding algorithm of malicious code based on multithreaded hyperchaos cipher encryption is proposed by combining hyperchaos Hénon mapping with multithreaded synchronization. Hiddenness factors of malicious code are analyzed, and a hiddenness analysis model of malicious code is proposed based on AHP.Gray pigeon malicious code is used to test and analyze the hiding algorithm of malicious code, and then the hiddenness analysis model of malicious code is used to analyze the experimental results. The results demonstrate the effectiveness of the malicious code hiding algorithm. The research in this paper increases the hiddenness and threat of malicious code, and it provides a new way for antivirus technologies.
