Abstract:In recent years, with the growth in the number of mobile platform users, mobile platform security has become the focal point in the field of information security. The virtualization extension of ARM, which facilitates the security of mobile platform based on virtualization technology, is a hot research topic. This paper first introduces the types of virtualization technology and previous related studies. Then the concepts of ARM virtualization extension are presented, and the comparison with the x86 virtualization extension is given as well. Subsequently, the paper focuses on the current situation of security research based on hardware virtualization extension, including the general system frameworks and security tools for specific attacks. Analysis of future's research trend of ARM virtualization-based security technology is put forward at the end.
