Self-authenticating chip

A method for providing an authenticating service of a chip, the method comprising:

• retrieving an intrinsic feature associated with a chip at a self-test engine;
• generating a first authentication value using the intrinsic feature at the identification engine;
• storing the first authentication value in memory;
• generating a second authentication value at the self-test engine using an authentication challenge;
• comparing the first authentication value and the second authentication value at a compare circuitry;
• and
• generating an authentication output value at the compare circuitry based on the results of the compare of the first authentication value and the second authentication value.

A method for deploying a system for providing an authenticating service of a chip, the system comprising:

• an authentication device comprising an identification engine, a self-test engine, and an intrinsic component associated with a chip and has an intrinsic feature;
• the self-test engine configured to retrieve the intrinsic feature and communicate the intrinsic feature to the identification engine;
• the identification engine configured to receive the intrinsic feature, generate a first authentication value using the intrinsic feature, and store the first authentication value in memory;
• the self-test engine further configured to generate a second authentication value using an authentication challenge,
• the identification engine further comprising a compare circuitry configured to compare the first authentication value and the second authentication value;
• and
• the compare circuitry further configured to generate an authentication output value based on the results of the compare of the first authentication value and the second authentication value.
