Q

Trusted Foundry

A

A microprocessor manufacturing utility that is part of a validated supply chain (one where hardware and software does not deviate from its documented function)

Trusted Foundry Program is operated by the Department of Defense (DoD)

Q

Hardware Source Authenticity

A

The process of ensuring that hardware is procured tamper-free from trustworthy suppliers

Greater risk of inadvertently obtaining counterfeited or compromised devices when purchasing from second-hand or aftermarket sources

Q

Hardware ROT

A

Hardware Root of Trust:
A cryptographic module embedded within a computer system that can endorse trusted execution and attest to boot settings and metrics

A hardware root of trust is used to scan the boot metrics and OS files to verify their signatures, which we can then use to sign a digital report

HSM

A

Hardware Security Module:
An appliance for generating and storing cryptographic keys that is less susceptible to tampering and insider threats than software-based storage

Q

Anti-Tamper

A

Methods that make it difficult for an attacker to alter the authorized execution of software

Anti-tamper mechanisms include a field programmable gate array (FPGA) and a physically unclonable function (PUF)

Q

UEFI

A

Unified Extensible Firmware Interface:
A type of system firmware providing support for 64-bit CPU operation at boot, full GUI and mouse operation at boot, and better boot security

Basically a new-and-improved BIOS

Q

eFUSE

A

A means for software or firmware to permanently alter the state of a transistor on a computer chip

Basically, the fuse will blow if the state of the software/firmware is modified

Q

Bus Encryption

A

Data is encrypted by an application prior to being placed on the data bus

Ensures that the device at the end of the bus is trusted to decrypt the data
