Claims10
An assembly, comprising:
- a micro-electro-mechanical system as physical unclonable function, which in reaction to a challenge, outputs a response in accordance with a mapping rule;
- and
- a controllable control element which is equipped, in accordance with a control command, to adjust an ambient parameter influencing the mapping rule.
A packaged unit, comprising:
- a plurality of assemblies each including a micro-electro-mechanical system as physical unclonable function, which in reaction to a challenge, outputs a response in accordance with a mapping rule, and a controllable control element which is equipped, in accordance with a control command, to adjust an ambient parameter influencing the mapping rule.
A system, comprising:
- at least one assembly, each of which includes a micro-electro-mechanical system as physical unclonable function, which in reaction to a challenge, outputs a response in accordance with a mapping rule, and a controllable control element which is equipped, in accordance with a control command, to adjust an ambient parameter influencing the mapping rule;
- and
- a control unit which is equipped to generate the control command for the control element.
