Modelling of Random Number Generator based on PUFs and LFSR for secret key generation

Random number generation give rise to a new set of random code or key in cryptography to run a variety of unpredictable tasks such as secret key generation. In this paper an Arbiter PUF along with LFSR is implemented which forms an anticipated True RNG. Outputs from LFSR and APUF are compared and a true cryptographic key is created in this work. This approach increases the uncertainty of the output pattern whilst the random and unpredictable bit stream couldn't replicate. The endeavor is implemented using Verilog HDL and formulated with Xilinx Vivado 2018.3 to inspect the maintenance of power and exceptionality of random number generation.
