Abstract
A method of authenticating a first electronic circuit includes generating a first signature using the first electronic circuit, the generating of the first signature being based on states of a plurality of electric nodes distributed within the first electronic circuit. A second signature is generated using a second electronic circuit, the generating of the second signature being based on states of a plurality of electric nodes distributed within the second electronic circuit. The first signature is compared to the second signature. The first electronic circuit is authenticated based on the comparison of the first signature to the second signature.
