<nowiki>:</nowiki> a chip that controls the device's main processor can only run software signed by the device manufacturer. This chip allows applications to use a technique called hardware attestation to detect if the operating system has been tampered in any way and in such a case block functionality or refuse to work altogether. If done properly hardware attestation is impossible to spoof, even by the device's owner. | <nowiki>:</nowiki> a chip that controls the device's main processor can only run software signed by the device manufacturer.
