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.
A Trusted Platform Module (TPM) is a secure cryptoprocessor that implements the ISO/IEC 11889 standard. Common uses are verifying that the boot process starts from a trusted combination of hardware and software and storing disk encryption keys. A TPM 2.0 implementation is part of the Windows 11 system requirements. [1]
Intel Software Guard Extensions (SGX) is a set of instruction codes implementing trusted execution environment that are built into some Intel central processing units (CPUs). They allow user-level and operating system code to define protected private regions of memory, called enclaves .
Intel AMT is the set of management and security features built into vPro PCs that makes it easier for a sys-admin to monitor, maintain, secure, and service PCs. [11] Intel AMT (the management technology) is sometimes mistaken for being the same as Intel vPro (the PC "platform"), because AMT is one of the most visible technologies of an Intel vPro-based PC.
The Intel Classmate PC (a competitor to the One Laptop Per Child) includes a Trusted Platform Module. [53] PrivateCore vCage software can be used to attest x86 servers with TPM chips. Mobile T6 secure operating system simulates the TPM functionality in mobile devices using the ARM TrustZone technology. [54]
The Open Mobile Terminal Platform (OMTP) first defined TEE in their "Advanced Trusted Environment:OMTP TR1" standard, defining it as a "set of hardware and software components providing facilities necessary to support applications," which had to meet the requirements of one of two defined security levels. The first security level, Profile 1 ...
The Intel Management Engine (ME), also known as the Intel Manageability Engine, [1] [2] is an autonomous subsystem that has been incorporated in virtually all of Intel's processor chipsets since 2008. [1] [3] [4] It is located in the Platform Controller Hub of modern Intel motherboards.
On October 11, 1999, the Trusted Computing Platform Alliance (abbreviated as TCPA), a consortium of various technology companies including Compaq, Hewlett-Packard, IBM, Intel, and Microsoft, was formed in an effort to promote trust and security in the personal computing platform. [4]
