DICE

Full Title

Device Identifier Composition Engine

Context

DICE is designed to the absolute minimum root of trust for programmable devices. Although it can do some TPM-stuff, it's mostly the root-of-trust on which to build things like TPMs (which are themselves pretty complicated.)

Many/most CPUs now have DICE support, although for more powerful CPUs it tends to be hidden away

DICE | Trusted Computing Group - Modern cyber-attacks are often sophisticated and relentless in their continual efforts to seek out vulnerabilities in modern technology-based solutions. At the same time, new market segments like the Internet of Things (IoT), are driving innovative architectures and creating solutions with challenging power, security, resource, and other constraints.

• DICE: Device Identifier Composition Engine - Microsoft Research aka RIoT (Robust | Resilient | Recoverable – IoT)
• There's a new sort of DICE called a DICE Protection Environment that's being driven by Google that's closer to a mini-TPM. This will also be a TCG standard in a few weeks.
