| 研究開始時の研究の概要 |
Even though video games have strong performance requirements, protecting online video games by leveraging TEEs is not a trivial task due to the inherent limitations of TEEs: (i) memory size limitation; (2) no direct access to I/O operations; and (3) non-negligible performance overhead to ensure security properties of the TEE. The challenges of this research project are thus three-fold: 1) how to design an effective method to partition the game code into a secure and unsecure part, to keep the memory footprint small; 2) how to provide trusted I/O; and 3) how to ensure acceptable performance.
|
| 研究実績の概要 |
- Several rounds of submission to Usenix S&P and CCS, but no accept so far.
- Paper accepted at the SysTEX '23 workshop.
- Research paper submitted to the SysTEX '24 workshop, but unfortunately not accepted.
- Started working on securing I/O by leveraging the ARM TrustZone TEE so that a cheater cannot automate his gameplay (e.g., running an aimbot).

3: やや遅れている
理由
Current results have not been accepted yet to a top-level international conference, so we have to spend more time to strengthen the paper.
In parallel we are continuing working on the other tasks related to the project: small secure memory and absence of trusted I/O.
|
| 今後の研究の推進方策 |
Small secure memory: we are actively working on the implementation and evaluation of our solution. We are currently using Qemu, but plan to eventually evaluate our solution on a real RISC-V board.
Trusted I/O: we are working on the implementation of a new system where I/O is protected against a strong attacker, so that a cheater cannot automate his cheats (e.g., running an aimbot). Results with the current prototype, leveraging ARM TrustZone, look promising.
