[8] [14] NGSCB has yet to fully materialize; however, aspects of it are available in features such as BitLocker of Windows Vista, Measured Boot and UEFI of Windows 8, [15] Certificate Attestation of Windows 8.1, [16] Device Guard of Windows 10. [17] and Device Encryption in Windows 11 Home editions, with TPM 2.0 mandatory for installation.
A fix was proposed, which has been adopted in the specifications for TPM 2.0. In 2009, the concept of shared authorisation data in TPM 1.2 was found to be flawed. An adversary given access to the data could spoof responses from the TPM. [67] A fix was proposed, which has been adopted in the specifications for TPM 2.0.
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 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.
The 3 series has replaced the 5 series as the budget line. Dell has also since dropped the E from the Latitude line (due to switching to a USB C/Thunderbolt dock system, rather than the e-Port analog pin-system docks), and the models are delineated by number now, e.g.: Latitude 5480, 5570.
The ROCA vulnerability is a cryptographic weakness that allows the private key of a key pair to be recovered from the public key in keys generated by devices with the vulnerability.
The key used for disk encryption is sealed (encrypted) by the TPM chip and will only be released to the OS loader code if the early boot files appear to be unmodified. The pre-OS components of BitLocker achieve this by implementing a Static Root of Trust Measurement—a methodology specified by the Trusted Computing Group (TCG).
In 1996 Renault used the Michelin PAX system [5] for the Scenic and in 1999 PSA Peugeot Citroën decided to adopt TPM as a standard feature on the Peugeot 607. The following year (2000), Renault launched the Laguna II , the first high volume mid-size passenger vehicle in the world to be equipped with TPM as a standard feature.
