Design and Analysis Memristor based Ring Oscillators True Random Number Generator

Abstract

Random number generation is an important part of cryptography because there are flaws in random number generation that can be taken advantage by attackers that compromised encryption systems that are algorithmically secure. True random number generators (TRNGs) are the best in producing random numbers. TRNGs works by measuring a controlled and organized physical process and the randomness of TRNG can be accurately categorized and measured. This paper presents a memristor based ring oscillator TRNG which uses different prime number of inverters. All of the ring oscillators (ROs) were designed using LT SPICE 0.18 µm model technology by Silterra. Performance calculation demonstrated that the output random numbers produced by the proposed TRNG have the performance parameters uniqueness of 49.778%, bit-aliasing of 44% and uniformity of 44%.
