SecureFS: A Secure File System for Intel SGX
Sandeep Kumar, Smruti R. Sarangi · 2021
A trusted execution environment or a TEE facilitates the secure execution of an application on a remote untrusted server. In a TEE, the confidentiality, integrity, and freshness properties for the code and data hold throughout the execution. In a TEE setting, specifically Intel SGX, even the operating system (OS) is not trusted. This results in certain limitations of a secure application’s functionality, such as no access to the file system and network – as it requires OS support.
