Trusted Execution Technology
Intel Trusted Execution Technology (Intel TXT, formerly known as LaGrande Technology) is the name of a computer hardware technology whose primary goals are:
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. 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 and/or BIOS code, or modifying the platform's configuration.
