LATTE is a framework designed to ensure both security and portability for attesting portable TEE applications. This repository is a prototype implementation, which uses WebAssembly as a portable intermediate representation and supports heterogeneous TEEs such as Intel SGX and RISC-V Penglai.

liblatte is a lightweight, standalone library for implementing layered attestation in portable enclaved applications. The repository includes core APIs for measurement and identity derivation, deployment utilities, and performance evaluation.

WAMR (wasm-micro-runtime) is a lightweight standalone WebAssembly runtime. In this repository, We implemented two WASM APIs : latte_attest and latte_verify. We also offered example of integrating LATTE into Genann, a minimal artificial neural networks program.

In these repositories, we selected SGX and Penglai as exemplar heterogeneous TEEs, modified SGX SDK (version 2.23) and Penglai TVM (commit bf52983) to support our framework.
