Direct Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user. . The protocol has been adopted by the Trusted Computing Group (TCG) in the latest version of its Trusted Platform Module (TPM) specification [1] to address privacy concerns (see also Loss of Internet anonymi
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. [69] A fix was proposed, which has been adopted in the specifications for TPM 2.0.
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.
There is concern amongst critics that it will not always be possible to examine the hardware components on which Trusted Computing relies, the Trusted Platform Module, which is the ultimate hardware system where the core 'root' of trust in the platform has to reside. [10] If not implemented correctly, it presents a security risk to overall ...
For mobile devices that can be stolen and attackers gain permanent physical access (paragraph Attacker with skill and lengthy physical access) Microsoft advise the use of pre-boot authentication and to disable standby power management. Pre-boot authentication can be performed with TPM with PIN protector or any 3rd party FDA vendor.
A Texas police officer was killed in the line of duty after being shot during a traffic stop, according to his department. Terrell Police Department Officer Jacob Candanoza, 28, died on Monday ...
The PSP is an integral part of the boot process, without which the x86 cores would never be activated. On-chip phase Firmware located directly on the PSP chip sets up the ARM CPU, verifies the integrity of the SPI ROM, using various data structures locates the off-chip firmware (AGESA) from the SPI ROM, and copies it over to internal PSP memory.
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed.
