Abstract
Disclosed are methods, systems and devices for implementing built-in self-test (BIST) to be performed by an untrusted party and/or in an unsecure testing environment. In an embodiment, a test access port (TAP) on a device may enable a party to initiate execution of one or more BIST procedures on the device. Additionally, such a TAP may enable loading of encrypted instructions to be executed by one or more processors formed on a device under test.
