Outline of Research at the Start |
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.
