 ==How it works==
-Phones and PCs include a Trusted Platform Module
+Phones and PCs include a Trusted Platform Module: a chip that controls the device's main processor can only run software signed by the device manufacturer.

If done properly hardware attestation is impossible to spoof, even by the device's owner.
