Dear all, I have an Arbiter PUF with reliability of 99.58%. Suppose I have 256 input to the PUF which generates 256 responses as an output. Now, I want to replace the 50% of input bits with 50% of response bits, randomly. In fact, I create a feedback loop between the output and input of the Arbiter PUF. My question is that what is the reliability of my new PUF instance?
I believe that the reliability of the new PUF may be less than 99.58%, because the error may get propagated from the output to the input of PUF.
