+title: Intel SGX Technology
+description:
+  Learn about Intel Software Guard Extensions (SGX) - the first-generation TEE
+  technology
+---
+
+# 🛡️ Intel SGX Technology
+
+**Intel® Software Guard Extensions (Intel® SGX)** is the first-generation TEE
+technology that enables **Trusted Computing** and **Confidential Computing**. On
+the iExec platform, SGX is the **production-ready, widely-supported TEE
+technology** that powers secure, privacy-preserving applications in the
+decentralized cloud.
+
+## Why SGX Matters for iExec
+
+iExec has chosen SGX as its primary TEE technology because it provides the
+perfect balance of **security, stability, and accessibility** for decentralized
+computing:
+
+### 🔒 **Decentralized Security**
+
+- **Hardware-Level Protection**: SGX provides hardware-level security guarantees
+  regardless of who owns the worker hardware
+- **Trust in Untrusted Environments**: Users can trust computation results even
+  from unknown workers in the network
+- **Proof of Contribution**: SGX enables verifiable proof that computations were
+  executed correctly
+
+### 💰 **Data Monetization Platform**
+
+- **Protected Data Processing**: Data owners can safely monetize their data
+  without losing control
+- **Secure Computation**: Sensitive data remains encrypted during processing
+- **Access Control**: Fine-grained control over who can access and process data
+
+### 🌐 **Global Computing Network**
+
+- **Wide Worker Support**: SGX is supported by the majority of iExec workers
+- **Reliable Execution**: Production-ready technology with proven stability
+- **Cost-Effective**: Standard pricing due to wide availability
+
+## What is Intel SGX?
+
+[Intel® SGX](https://software.intel.com/en-us/sgx) is a technology that enables
+**Trusted Computing** and **Confidential Computing**. At its core, it relies on
+the creation of a special zone in the memory called an "enclave". This enclave
+can be considered as a vault, to which only the CPU can have access. Neither
+privileged access-levels such as root, nor the operating system itself is
+capable of inspecting the content of this region. The code, as well as the data
+inside the protected zone, is totally unreadable and unalterable from the
+outside. This guarantees non-disclosure of data as well as tamper-proof
+execution of the code.
+
+An application's code can be separated into "trusted" and "untrusted" parts
+where sensitive data is manipulated inside the protected area.
+
+## SGX: The "Application-Level" Security
+
+**Intel SGX** is like having a **small, specialized safe** inside your office
+for specific valuable items. It protects individual applications or parts of
+applications.
+
+### Key Characteristics
+
+- **Scope**: Protects specific parts of your application
+- **Memory**: Limited secure memory (like a small safe)
+- **Code Changes**: Requires significant modifications to your application
+- **Use Case**: Perfect for focused, lightweight applications
+
+**Analogy**: SGX is like installing a small, specialized safe inside your office
+for specific valuable items.

+```
+
+## SGX Technology Details
+
+### How SGX Works
+
+1. **Enclave Creation**: SGX creates a secure memory region (enclave) that only
+   the CPU can access
+2. **Code Isolation**: Sensitive code runs inside the enclave, isolated from the
+   rest of the system
+3. **Memory Encryption**: All data in the enclave is automatically encrypted
+4. **Integrity Protection**: The enclave can prove it's running the correct,
+   unmodified code
+
+### SGX Limitations
+
+With native Intel® SGX technology, the OS is not a part of the Trusted
+Computing Base (TCB), hence system calls and kernel services are not available
+from an Intel® SGX enclave. This can be limiting as the application will not be
+able to use File System and sockets directly from the code running inside the
+enclave.
+
+## SGX with iExec and Scone
+
+iExec has built a comprehensive SGX infrastructure that makes it easy for
+developers to create secure, privacy-preserving applications without deep SGX
+expertise.
+
+### iExec's SGX Infrastructure
+
+iExec provides a complete SGX ecosystem that includes:
+
+- **🔐 Secret Management Service (SMS)**: Secure storage for encryption keys and
+  secrets
+- **🛡️ SGX Workers**: Computing nodes with SGX hardware support
+- **📋 Task Verification**: Proof of contribution system that verifies SGX
+  execution
+- **🔗 Blockchain Integration**: Decentralized coordination and payment
+- **📦 Scone Framework**: High-level development framework for SGX applications
+
+### Why iExec Uses Scone
+
+To build Confidential Computing (TEE) applications with SGX, iExec uses the
+high-level **Scone framework** instead of requiring developers to manipulate the
+Intel® SGX SDK directly.
+
+#### Scone Framework Benefits
+
+At a high-level, Scone protects the confidentiality and integrity of the data
+and the code without needing to modify or recompile the application. The
+[Scone](https://scontain.com/) framework resolves the limitations of native SGX
+and reduces the burden of porting the application to Intel® SGX.
+
+#### How Scone Works
+
+More precisely, Scone provides a C standard library interface to container
+processes. System calls are executed outside of the enclave, but they are
+shielded by transparently encrypting/decrypting application data. Files stored
+outside of the enclave are therefore encrypted, and network communication is
+protected by Transport Layer Security (TLS).
+
+For a deeper understanding, you can have a look to the official
+[Scone documentation](https://sconedocs.github.io/).
