Abstract: Attestation of an electronic device provides assurances that the device is trustworthy and operating as intended or, at least, within acceptable parameters. Methods and systems are provided herein wherein a device under test (DUT) is subject to tests, the results of which are provided to a trust verifier (TV) to indicate whether the DUT passed or failed. To protect the integrity of the test from being discovered by malware, the test logic is developed “off board” and only machine code is provided to the DUT. Similarly, memory values and other data of the DUT are not revealed to the TV, which is only provided with test results.
