Components of a Trusted Platform Module complying with the TPM version 1.2 standard. Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, a dedicated microcontroller designed to secure hardware through integrated cryptographic keys.
Note the CRIME security exploit takes advantage of TLS compression, so conservative implementations do not enable compression at the TLS level. HTTP compression is unrelated and unaffected by this exploit, but is exploited by the related BREACH attack.
PCR values are available both locally and remotely. 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.
Windows 10 is the last version of Microsoft Windows that supports 32-bit processors (IA-32 and ARMv7-based), the last non-IoT edition to officially lack a CPU whitelist [30] and support BIOS firmware, [31] [32] and the last version to officially support systems with TPM 1.2 or without any TPM at all.
This key is used to allow the execution of secure transactions: every Trusted Platform Module (TPM) is required to be able to sign a random number (in order to allow the owner to show that he has a genuine trusted computer), using a particular protocol created by the Trusted Computing Group (the direct anonymous attestation protocol) in order ...
The CPU includes the TPM, or trusted platform module, version 1.2. Like the Surface Pro, the Surface Pro 2 has a gyroscope, accelerometer, ambient light sensor, compass, 2 720p Lifecam cameras, and stereo speakers.
[19] [40] TPM 1.2 was designed for compliance with NGSCB [41] and introduced many features for such platforms. [42] The first TPM 1.2 specification, Revision 62 was released in 2003. [43] Biddle emphasized in June 2003 that hardware vendors and software developers were vital to NGSCB. [44]
Transparent operation mode: This mode uses the capabilities of TPM 1.2 hardware to provide for transparent user experience—the user powers up and logs into Windows as usual. 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.
