A Morphable Physically Unclonable Function and True Random Number Generator Using a Commercial Magnetic Memory

We use commercial magnetic memory to realize morphable security primitives, a Physically Unclonable Function (PUF) and True Random Number Generator (TRNG). The PUF realized by manipulating the write time TRNG is tweaking number of pulses. Our analysis indicates that more than 75% bits in are unusable without any correction due their inability exhibit randomness. exploit temporal randomness working columns fix latency rows during enrollment. intra-HD, inter-HD, energy, bandwidth area proposed found be 0, 46.25%, 0.14 pJ/bit, 0.34 Gbit/s 0.385 μm2/bit (including peripherals) respectively. provides all possible outcomes with standard deviation 0.0062, correlation coefficient 0.05 an entropy 0.95. 0.41 0.12 0.769 peripherals). performance has also been tested NIST test suite. designs compared other PUFs TRNGs from literature.
