【Abstract】 A chaotic true random number generator based on hybrid Boolean network was proposed. The entropy source is composed of an 18-node autonomous Boolean network, which is used to generate Boolean chaotic with high amplitude(～3 V) and large bandwidth(～780 MHz). The Boolean chaos is sampled and quantized by using a synchronous Boolean network, and finally a real random number with a real-time rate of 100 Mbps is generated. At the same time, the ASIC chip design of the true random data generator was completed. The chip adopts SMIC 0.35-μm 3.3 V CMOS standard process, and the core circuit area is 0.02 mm~2. Back-end simulation verification of the chip layout was performed using the Cadence Spectre simulator. The simulation results show that the chip can output a sequence of true random numbers satisfying the randomness detection standard at 100 MHz clock.更多还原
