WebAssembly + Confidential Computing

Talkat FOSDEM 2022 · on Saturday, 2022-02-05· at 10:55· D.trusted-hardware· [webassembly]

Enarx 1.0 integrates a wasmtime-based WebAssembly runtime into a Confidential Computing deployment framework to run applications inside TEEs called “Keeps.” It enables running Rust, C, C++ (and other languages targeting WebAssembly) across multiple hardware TEEs—Intel SGX/TDX, AMD SEV, and future platforms like ARM Realms and IBM PEF—without rewriting or separately handling attestation, using WebAssembly’s sandboxing to add isolation. Demos showing these benefits are presented.
