Enarx

Enarx provides a platform abstraction for Trusted Execution Environments (TEEs) enabling creating and running “private, fungible, serverless” applications.

Open Enclave SDK

Open Enclave SDK is an open source framework that allows developers to build Trusted Execution Environment (TEE) applications using a single enclaving abstraction.

Keystone

Keystone is an open-source project for building trusted execution environments (TEE) with secure hardware enclaves, based on the RISC-V architecture. Our goal is to build a secure and trustworthy open-source secure hardware enclave, accessible to everyone in industry and academia.

Veracruz

Veracruz is a research project exploring the design of privacy-preserving distributed systems.  Veracruz uses strong isolation technology and remote attestation protocols to establish a “neutral ground” within which a collaborative, multi-party computation between a group of mistrusting principals takes place.

Gramine

A particular use case for Gramine is Intel Software Guard Extensions (SGX), where applications do not work out-of-the-box. Gramine solves this problem, with the added security benefits. Gramine can serve as a compatibility layer on other platforms.

Occlum

Occlum makes running applications inside enclaves easy. It allows one to run unmodified programs inside enclaves with just a few simple commands. And Occlum is open-source and free to use.
