Abstract
A system and device for verifying the integrity of a system from its subcomponents, the system comprising a plurality of subcomponents each having a physical state, the system and the device comprising a processor that is connected to each of the subcomponents, the processor configured to verify systemic integrity by performing verification on some or all specified subcomponents. The verification may be individual (1,1) or threshold (n,1), and may be interactive or non-interactive.

A device for verifying the integrity of a system comprising a plurality of subcomponents each having a physical state, the device comprising a processor that is connected to each of the subcomponents, the processor configured to verify systemic integrity by performing verification on some or all specified subcomponents.
A system for verifying systemic integrity, the system comprising:
- a. a plurality of subcomponents each having a physical state, and each including a physically-unclonable function (‘PUF’) device constructed to generate, in response to the input of a challenge, an output value that is characteristic to the PUF and the challenge;
- and
- b. a processor that is connected to each of the subcomponents, the processor configured to verify systemic integrity by performing verification on some or all specified subcomponents' PUFs.
