Protecting CPU AI On Edge TEEs: WebAssembly's Promise and Practical Challenges
The work presents a method to run unaltered AI models inside edge Trusted Execution Environments (TEEs) like OP-TEE for Arm TrustZone. It achieves this by compiling AI models to WebAssembly (Wasm) and using the WebAssembly Micro Runtime (WAMR) within OP-TEE. This allows secure execution of encrypted models, protecting intellectual property while addressing TEE constraints.
