TRUSTED EXECUTION TECHNOLOGY

'Trusted Execution Technology' (TET or TXT), formerly known as ''LaGrande Technology'' is a key component of Intel's initiative of ''"safer computing"''. Intel claims that it will be very useful, especially in the business world, as a way to defend against software-based attacks aimed at stealing sensitive information. Although commonly advertised by Intel as security technology, the Free Software Foundation claims that it can also be used to enable development of more advanced, tamper-resistant forms of DRM, and can be abused to achieve vendor lock-in.
It consists of a series of ''hardware enhancements'', to allow for the creation of multiple separated execution environments, or partitions. One component is a relatively new chip residing on the motherboard, called the TPM (Trusted platform module), which allows for secure key generation and storage, and authenticated access to data encrypted by this key. Note however, that the private key stored in the TPM is generally not available to the owner of the machine, and never leaves the chip under normal operation. The TPM additionally provides for a means of remote assurance of a machines security state. Another component is DMA page protection.
