Abstract:

he rapid development of mobile communication technology, not only presents new services and applications, but also attracts mobile phone viruses' attacks. For the above issues, this paper summarizes the mobile phone viruses' infection routes and common characteristics, compares the proposesed antivirus technologies, and presents a mobile phone virus defense technique based on heuristic behaviorchecking according to mobile phones' specialty. This method uses the hidden Markov model to heuristically analyze the behaviors of the application, so as to prevent the malicious behaviors of viruses, and protect the mobile phones' security.
