| Outline of Final Research Achievements |
A study was conducted on tamper resistant software creation method such that its algorithm can be public and be applicable to embedded systems. Its objective evaluation on practical usefulness became clear and its applicability was extended to not only PC but also embedded systems.
1. As tamper resistance technology applicable to embedded systems, we proposed a method to create tamper resistant software that can generate self destructive tamper response using data memory, based on indirect jump (jump destination is dynamically determined) and ROP (Return-Oriented Programming).
2. As implementation evaluation for personal computer, we developed a tool to create tamper resistant software of PC, conducted experiments using the tool, and evaluated the data obtained through experiments. It was confirmed that the tool worked as intended and created self destructive tamper resistant software has resistance to modification.
