Intel® Trusted Execution Technology

Intel® Trusted Execution Technology (Intel® TXT) for safer computing, formerly code named LaGrande Technology, is a versatile set of hardware extensions to Intel® processors and chipsets that enhance the platform with security capabilities such as measured launch and protected execution. Intel® TXT provides hardware-based mechanisms that help protect against software-based attacks and protects the confidentiality and integrity of data stored or created on the system. It does this by enabling an environment where applications can run within their own space, protected from all other software on the system. These capabilities provide the protection mechanisms, rooted in hardware, that are necessary to provide trust in the application's execution environment. In turn, this can help to protect vital data and processes from being compromised by malicious software running on the platform. Long available on client platforms, Intel is now enabling Intel TXT on selected server platforms as well.

In Dynamics of a Trusted Platform David Grawrock has updated his highly popular Intel Safer Computing Initiative with new topics covering the latest developments in secure computing using The Intel® Trusted Execution Technology (Intel® TXT). In this concise book, the lead architect for Intel's security initiative introduces the concept of Trusted Computing and the building block approach to designing security into PC platforms.

"This book is a good, understandable reference that manages to describe trusted computing without being dry." says Amy C Nelson, Advanced Engineer Security Devices of Dell Inc.
