Intel Trusted Execution Technology (Intel TXT, formerly known as LaGrande Technology) is a computer hardware technology of which the primary goals are:

• Attestation of the authenticity of a platform and its operating system.
• Assuring that an authentic operating system starts in a trusted environment, which can then be considered trusted.
• Provision of a trusted operating system with additional security capabilities not available to an unproven one.

Intel TXT uses a Trusted Platform Module (TPM) and cryptographic techniques to provide measurements of software and platform components so that system software as well as local and remote management applications may use those measurements to make trust decisions. It complements Intel Management Engine. This technology is based on an industry initiative by the Trusted Computing Group (TCG) to promote safer computing. It defends against software-based attacks aimed at stealing sensitive information by corrupting system or BIOS code, or modifying the platform's configuration.
