This work presents a fast, low power and simple structure noise-based true random number generator (TRNG) using discrete components and devices such as resistor., capacitor, diode., transistor., operational amplifier etc. Two NPN 2N3904 BJT transistors are employed in the noise-source circuit whereby the collector terminal of one transistor is unconnected. A high electric field is induced by reverse biasing the emitter-base junction under high voltage. Current is injected into the base which lowers the noise voltage at the output node and then removes the transistor from breakdown region. Another random pulse also puts the transistor back into breakdown and the cycle continues. Subsequently, the noise signal generated is amplified by two LM741 op-amp each with a gain of 100. We employed 4007 series as digitizer to convert the amplified noise to digital pulses. The post processing technique is implemented with XOR operation., and the result shows the output data generated by TRNG pass all NIST SP800-22 tests.

A self-reference resistive random-access memory (ReRAM)-based one-transistor, two-ReRAM (1T2R) physically unclonable function (PUF) is proposed to provide a hardware security feature for electrical products in the IoT/5G era. There are four advantages from the proposed structure: (1) a small cell size; (2) intrinsic randomness; (3) no programming circuit; and (4) no data retention concerns. The conduction mechanism, temperature dependency, and read fluctuation of the pristine ReRAM device are studied. An information–address separation scheme is proposed which not only reduces the impact of the read noise and the temperature effect, but also improves system integrity against hardware attacks. The proposed 1T2R PUF unit also has great potential for use as a random seed for linear-feedback shift registers in pseudo random number generators with high unpredictability, good randomness, and a high data rate.
