Introduction
As the landscape of data security continues to evolve, the concept of a Library OS (operating system) for Confidential Computing is gaining traction. Library OS projects create secure environments for applications by providing “auto” enclaves for process isolation. These enclaves, also known as runtimes or sandboxes, ensure that sensitive data remains protected even during processing. In this blog, we explore the significance of Library OS for confidential computing and highlight three key projects: Gramine, Occlum, and Enarx.
What is a Library OS?
A Library OS, or “libOS,” is a streamlined operating system that runs applications within secure enclaves. These enclaves isolate processes, providing a trusted execution environment (TEE) that safeguards data from unauthorized access and tampering. This approach is particularly valuable for confidential computing, where data must remain secure throughout its lifecycle, including during computation.
Key Projects in Library OS for Confidential Computing
Gramine
- Overview: Gramine is an open-source Library OS designed to run applications in trusted execution environments. It supports Intel SGX and enables the secure execution of unmodified applications.
- Features: Gramine provides robust security by isolating applications within enclaves, ensuring that data remains protected even if the underlying host is compromised. Its compatibility with existing applications makes it a versatile choice for enhancing data security.
- GitHub: Gramine Project
Occlum
- Overview: Occlum is a memory-safe, multi-process Library OS that supports Intel SGX. It aims to provide a secure and efficient environment for running applications within enclaves.
- Features: Occlum ensures data confidentiality and integrity by isolating processes and providing strong security guarantees. Its design focuses on performance and scalability, making it suitable for a wide range of applications.
- GitHub: Occlum Project
Enarx
- Overview: While not a traditional Library OS, Enarx uses WebAssembly (Wasm) to provide similar benefits. It enables the secure execution of applications in TEEs, ensuring data privacy and integrity.
- Features: Enarx leverages Wasm to create secure runtimes that can run across different hardware platforms. Its approach simplifies the deployment of secure applications, making it a compelling option for confidential computing.

The Importance of Library OS in Confidential Computing
Library OS projects like Gramine, Occlum, and Enarx play a crucial role in the realm of confidential computing. They offer a layer of security that ensures sensitive data remains protected during processing. By isolating applications within secure enclaves, these projects mitigate risks associated with data breaches and unauthorized access.
Conclusion
The concept of a Library OS for confidential computing represents a significant advancement in data security. Projects like Gramine, Occlum, and Enarx demonstrate the potential of this approach to enhance privacy and protect sensitive information. As the need for secure data processing continues to grow, these projects will play an increasingly vital role in ensuring the confidentiality and integrity of data in various applications.
