Intel Trusted Execution Technology (TXT), formally codenamed LaGrande, is set of hardware extensions to Intel processors and chipsets that, with appropriate software, enhance the platform security capabilities. Trusted Execution Technology provide a hardware-based security foundation that will help enable greater levels of protection for information stored, processed and exchanged on the PC.

It includes :
- Protected execution and memory spaces where sensitive data can be processed out of view of any other software.
- Sealed storage shields encryption keys and other data from attack while in use or stored.
- Attestation enables a system to provide assurance that it has correctly invoked the Intel Trusted Execution Technology environment, as well as enable a verified measurement of the software running in the protected space.

Used for : Intel Core i5, Intel Core i7, Intel Core i9, Intel Core M, Intel Xeon
