Abstract
A method for using an identification value for a security application is disclosed. The method may include the steps of (A) generating the identification value based on a plurality of semiconductor fabrication process variations, (B) generating a key by reducing a bit error rate of the identification value, wherein the key may not be available external to the security application and (C) generating an output signal by one of (i) encoding and (ii) decoding an input signal in response to said key.
