  Physical Unclonable Functions (PUFs) are widely used to generate random
Numbers. In this paper we propose a new architecture in which an Arbiter Based
PUF has been employed as a nonlinear function in Nonlinear Feedback Shift
Register (NFSR) to generate true random numbers. The rate of producing the
output bit streams is 10 million bits per second. The proposed RNG is able to
pass all NIST tests and the entropy of the output stream is 7.999837 bits per
byte. The proposed circuit has very low resource usage of 193 Slices that makes
it suitable for lightweight applications.
