Introduction to Gramine

Gramine is a lightweight guest OS, designed to run a single Linux application with minimal host requirements. Gramine can run applications in an isolated environment with benefits comparable to running a complete OS in a virtual machine – including guest customization, ease of porting to different host OSes, and process migration.

Gramine supports running Linux applications using the Intel SGX (Software Guard Extensions) technology (we sometimes call this version Gramine-SGX). With Intel SGX, applications are secured in hardware-encrypted memory regions (called SGX enclaves). SGX protects code and data in the enclave against privileged software attacks and against physical attacks on the hardware off the CPU package (e.g., cold-boot attacks on RAM). Gramine is able to run unmodified applications inside SGX enclaves, without the toll of manually porting the application to the SGX environment.
