Intel Software Guard Extensions (SGX) is a set of security-related instruction codes that are built into some Intel central processing units (CPUs). They allow user-level and operating system code to define protected private regions of memory, called enclaves. SGX is designed to be useful for implementing secure , secure web browsing, and digital rights management (DRM). Other applications include concealment of proprietary algorithms and of encryption keys.

rdfs:comment	Intel Software Guard Extensions (SGX) è un insieme di codici di istruzioni dell'unità di elaborazione centrale (CPU) di Intel che consente al codice a livello utente di allocare regioni private di memoria, chiamate enclave, che sono protette da processi in esecuzione a livelli di privilegio più elevati. Intel ha progettato SGX per essere utile nell'implementare il calcolo remoto sicuro, la navigazione web sicura e la gestione dei diritti digitali (DRM). (it) 英特尔软件防护扩展（英語：Intel Software Guard Extensions，SGX）是一组，它被内置于一些现代Intel 中央处理器（CPU）中。它们允许用户态及内核态代码定义将特定内存区域，设置为私有区域，此区域也被称作飞地（Enclaves）。其内容受到保护，不能被本身以外的任何进程存取，包括以更高权限级别运行的进程。 CPU对受SGX保护的内存进行加密处理。受保护区域的代码和数据的加解密操作在CPU内部动态（on the fly）完成。因此，处理器可以保护代码不被其他代码窥视或检查。SGX使用的威胁模型如下：Enclaves是可信的，但Enclaves之外的任何进程都不可信（包括操作系统本身和任何虚拟化管理程序），所有这些不可信的主体都被视为有存在恶意行为的风险。Enclaves之外代码的任何代码读取受保护区域，只能得到加密后的内容。由于SGX不能防止针对运行时间等侧信道信息的测量和观察，在SGX内部运行的程序本身必须能抵抗侧信道攻击。 SGX被设计用于实现安全远程计算、安全网页浏览和数字版权管理（DRM）。其他应用也包括保护专有算法和加密密钥。 (zh) Die Software Guard Extensions (Intel SGX) sind eine Erweiterung der x86-Architektur, um sichere Enklaven zu erstellen. Diese sind Bereiche im Adressraum eines Prozesses, die speziell durch die CPU geschützt werden und für die alle direkten Zugriffe, auch von privilegierten Prozessen, durch die CPU kontrolliert bzw. verhindert werden. Der Schutz des SGX-Speichers umfasst unter anderem transparente Speicherverschlüsselung mit Integritätsschutz. In den skalierbaren Xeon-Prozessoren der 3. Generation (Ice Lake SP) sind die SGX weiterhin vorhanden.

(en) O SGX ( Software Security Guard Extensions ) da Intel é um conjunto de códigos de instruções relacionados à segurança incorporados em algumas unidades de processamento central (CPUs) modernas da Intel . Eles permitem que o código do sistema operacional e do usuário definam regiões privadas da memória, denominadas enclaves, cujo conteúdo é protegido e não pode ser lido ou salvo por qualquer processo fora do próprio enclave, incluindo processos executados em níveis de privilégios mais altos . O SGX está desativado por padrão e deve ser aceito pelo usuário por meio de suas configurações de BIOS em um sistema suportado. (pt) Расширения Intel Software Guard Extensions (Intel SGX) — набор инструкций центрального процессора, предоставляющих возможность приложению создавать анклавы — области в виртуальном адресном пространстве, защищённые от чтения и записи извне этой области другими процессами, включая ядро операционной системы. Intel SGX обеспечивают целостность и конфиденциальность вычислений с повышенными требованиями к безопасности, производимыми на системах, где привилегированные процессы (ядро операционной системы, гипервизор, и т. д.) считаются ненадёжными.
