Trusted Execution Technology

Intel Trusted Execution Technology (TXT) is a security feature that is included in some newer Intel processors. It is designed to provide a hardware-based root of trust for the system, which can help to enhance the security and reliability of computer systems.

TXT works by creating a secure environment, or "trusted execution environment" (TEE), within the processor. This environment is isolated from the main system and is protected by hardware-based security mechanisms, such as secure boot and memory encryption. The TEE is used to perform critical security functions, such as launching and verifying the integrity of the operating system and other system components.

TXT also supports the use of trusted platform modules (TPMs), which are hardware-based security devices that store cryptographic keys and other sensitive information. TPMs can be used to provide additional security functions, such as secure storage, secure boot, and remote attestation.

Overall, Intel TXT is an important security feature that can help to enhance the security and reliability of computer systems, particularly in business and enterprise environments where security threats are a significant concern. It provides a hardware-based root of trust that can be used to secure critical system components and protect sensitive data from a range of security threats, including malware, rootkits, and other types of attacks.
