Random Numbers are needed to generate the essential seed for encryption in secure communication systems. If the randomness of the seed is compromised, this may eventually load to comprising the entire encryption method. The global cybercrime is expected to reach up to 10.5 Trillion USD by 2025. Furthermore, the demand for high rates of random numbers is also increasing as several billion IoT devices are getting connected to the Internet. A True Random Number Generator (TRNG) extracts entropy from physical phenomenon rather than mathematical algorithms like a PRNG, hence it is more reliable for seed generation. The state-of-the-art TRNGs are either limited in speed (up to 1.5 to 2 Gbps) or require very high power for high data rates (up to 200 mW) due to high static power consumption. However, high speed and low power are highly desirable in the next generation of 5G/6G communication systems and IoT applications.
