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]
According to an AMD developer's guide, the subsystem is "responsible for creating, monitoring and maintaining the security environment" and "its functions include managing the boot process, initializing various security related mechanisms, and monitoring the system for any suspicious activity or events and implementing an appropriate response". [2]
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.
The static information will uniquely identify the endorser of the platform, model, details of the TPM, and that the platform (PC) complies with the TCG specifications . The dynamic information is described as software running on the computer. [37] If a program like Windows is registered in the user's name this in turn will uniquely identify the ...
BitLocker uses a low-level device driver to encrypt and decrypt all file operations, making interaction with the encrypted volume transparent to applications running on the platform. [41] Encrypting File System (EFS) may be used in conjunction with BitLocker to provide protection once the operating system is running. Protection of the files ...
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 Root System Description Pointer (RSDP) is located in a platform-dependent manner, and describes the rest of the tables. A custom ACPI table called the Windows Platform Binary Table (WPBT) is used by Microsoft to allow vendors to add software into the Windows OS automatically.
The TCPA released detailed specifications for a trusted computing platform with focus on features such as code validation and encryption based on integrity measurements, hardware-based key storage, and machine authentication; these features required a new hardware component designed by the TCPA called the "Trusted Platform Module" (referred to ...
