A new dual entropy core true random number generator

An Integrated Dual Entropy Core True Random Number Generator

“…Cicek shown in Fig. 2 which achieves higher entropy levels with better immunity to parameter variations [3]. We showed that the distribution of the difference of two uniformly distributed random variables will be inherently symmetric with zero mean which allows the use of any endomorphic chaotic map with a uniform underlying distribution as an entropy source.…”

“…Throughput, and dynamic power consumption can be controlled by the clock signal to meet the design requirements of high speed, or low power scenarios without requiring any topological changes. We used two different maps with uniform underlying distribution as entropy sources to show the validity of the theoretical calculations in [3].…”

“…Multiple oscillator sampling based TRNGs address throughput problem at the expense of high power consumption which restrict their use in emerging lightweight cryptographic applications [2]. Discrete time chaos (DTC) based TRNGs can be realized using much less resources, which render them a convenient choice for these applications [3]. However, they come with drawbacks of their own.…”

“…A typical single entropy core DTC based TRNG architecture shown in Fig. 1 has a parameter variation sensitive randomness performance [3]. Theoretical maximum entropy levels are not achievable in practice, due to inevitable parameter variations.…”

“…We showed that the distribution of the difference of two uniformly distributed random variables will be inherently symmetric with zero mean which allows the use of any endomorphic chaotic map with a uniform underlying distribution as an entropy source. A proof of the concept prototype using two Bernoulli maps was successfully implemented on an FPAA chip [3]. In this paper, we present a novel design approach, and the first integrated circuit implementation of the dual entropy core TRNG architecture which employs two different chaotic maps with uniform underlying distribution.…”
