Device Identifier Composition Engine: a Trusted Computing Group standard that gives small devices an identity derived from their firmware.
DICE derives each boot layer's identity from the measurement of the next one. Change the firmware and the identity changes, which makes updates and re-attestation explicit by design. It suits microcontrollers and components where a full TPM is too costly.
Example. A sensor chip costing under a euro derives its identity from its firmware. Flash different firmware and it shows up as a different device.
