| Outline of Final Research Achievements |
We have demonstrated the effectiveness of a new security mechanism focusing on the OS and VMM, which are fundamental software of a computer, in the following research. First, we developed a VMM that can track the spread of classified information of a guest OS across multiple VMs. We also realized a method to protect OS kernel information and security mechanisms by using multiple virtual storage spaces, virtualization technology, and Arm's TrustZone. We have also developed a method for detecting and disabling privilege escalation in a guest OS. With these results, we have shown how to build a fundamental software technology that increases OS attack resistance and makes attacks on security mechanisms more difficult.
