Abstract:
A method and apparatus are provided for generating a unique identifier. One or more tests are performed over one or more data-dependent circuit paths for one or more circuits. The one or more tests are then repeated over the one or more data-dependent circuit paths for the one or more circuits while adjusting an operating frequency and/or operating voltage for each of the one or more circuits. A threshold frequency and/or threshold voltage is ascertained for each of the one or more data-dependent circuit paths. An identifier may then be generated based on a plurality of the threshold frequencies and/or threshold voltages ascertained for the one or more data-dependent circuit paths.
