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

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.

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.

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.

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

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.
