Secure Filesystem for Trusted Virtual Domain in Mobile Device

摘要

Recently, the development of smart phones has been reported the number of security vulnerabilities. In spite of these smart phones have a concept of Sandbox for the security, sensitive personal information has been still exposed by internal data exchange or root privilege acquisition. In this paper, we propose a domain group which is separated into general domain and trusted virtual domain (TVD) by virtualization techniques. TVD provides a secure execution environment in mobile device and makes it possible to protect sensitive personal information in the domain. Thus, we suggest together the secure filesystem in TVD to securely store and manage significant data of user. This results presented by secure filesystem based on TVD would raise expectation about the following security virtualization techniques.
