While TPM 1.2 parts are discrete silicon components, which are typically soldered on the motherboard, TPM 2.0 is available as a discrete (dTPM) silicon component in a single semiconductor package, an integrated component incorporated in one or more semiconductor packages - alongside other logic units in the same package(s), and as a firmware ...
Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software.
Motherboard hardware or chipset signaling via a designated pin SMI# of the processor chip. [16] This signal can be an independent event. Software SMI triggered by the system software via an I/O access to a location considered special by the motherboard logic (port 0B2h is common). [17]
In November 1999, the TCPA announced that over 70 leading hardware and software companies joined the alliance in the first month. [5] On January 30, 2001, version 1.0 of the Trusted Computing Platform Specifications was released [ 6 ] IBM was the first original equipment manufacturer to incorporate hardware features based on the specifications ...
The endorsement key is a 2048-bit RSA public and private key pair that is created randomly on the chip at manufacture time and cannot be changed. The private key never leaves the chip, while the public key is used for attestation and for encryption of sensitive data sent to the chip, as occurs during the TPM_TakeOwnership command.
Nuvoton designs and manufactures key chips for PC motherboards, laptops, and servers, offering super I/O components, clock generators, hardware monitoring, power management ICs. Notebook keyboard controllers , embedded controllers for mobile platforms and TPM security chips.
Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
The Trusted Platform Module (TPM) is an implementation of a secure cryptoprocessor that brings the notion of trusted computing to ordinary PCs by enabling a secure environment. [citation needed] Present TPM implementations focus on providing a tamper-proof boot environment, and persistent and volatile storage encryption.
