| Popis: | A true random number generator (TRNG) is proposed and evaluated by field-programmable gate arrays (FPGA) implementation that generates random numbers by exclusive-ORing (XORing) the outputs of many SR latches (Hata and Ichikawa, IEICE Trans. Inf. Syst. E95-D(2):426---436, 2012). This enables compact implementation and generates high-entropy random numbers. In this paper, we fabricate and evaluate 39 TRNGs using SR latches on 0.18 μm ASICs. Random numbers are generated by XORing the outputs of 256 SR latches. Our TRNGs pass the SP800-90B health tests and the AIS20/31 statistical tests in changing temperatures (from ?20 to 60 °C) and voltages (1.80 ± 0.15 V). We also perform an independent and identically distributed (IID) test and calculate min-entropy according to the SP800-90B. With these tests, we are able to confirm that our TRNGs are highly robust against environmental stress. The power consumption and circuit scale of our TRNGs are 0.27 mW and 1240.5 gates, respectively. Our TRNGs that use SR latches are small enough to be implemented in embedded devices. |
