On Real-Time Guarantees in Intel SGX and TDX Yuhala, Peterson Göttel, Christian Ménétrey, Jämes Schiavoni, Valerio Kozhaya, David Felber, Pascal Trusted execution environments Real-time systems Intel SGX Intel TDX WebAssembly Trusted execution environments (TEE) represent a major technological breakthrough that provide strong confidentiality and integrity guarantees for code and data running on potentially vulnerable or untrustworthy computing systems, such as cloud, edge, embedded, mobile, or even blockchain systems. However, the performance overhead associated with TEEs still poses a limitation on the extent to which real-time (RT) sensitive applications can benefit from this technology, e.g., to run on untrusted third-party infrastructures. This work investigates various TEE-based architectures spanning from process-based to virtual-machine-based implementations, for securing RT applications. It offers in addition an in-depth evaluation of these architectures, providing insights into how various TEE deployments influence the temporal compute and communication guarantees of RT systems.
