The Unclonable Device Identity That Makes Zero-Trust Devices Possible
From Episode 2: Why Initial Authentication Is Never Enough
In the previous post, we reached a critical conclusion:
Security is not complete with initial authentication alone.
For a Zero-Trust Device to exist, a device—and the software running on it—must be able to continuously prove that it is genuine, at every moment.
We also identified the foundation of this continuous trust:
Hardware Root of Trust (HRoT) — the anchor where device trust begins.
That leads to one essential question:
What should a Hardware Root of Trust be built on so that its identity cannot be forged, cloned, or stolen?
