In this paper we discuss the possible use of chaotic signals for testing Analog to Digital Converters (ADCs). In detail, exploiting a chaos-based discrete-time noise generator, a method for generating test samples with a distribution arbitrarly close to the uniform one is proposed, and their use for the Code Density Test (also known as Histogram Test) of ADC is discussed.
In this paper, a theoretical approach for studying the robustness of the chaotic statistics of piecewise affine maps with respect to parameter perturbations is discussed. The approach is oriented toward the study of the effects that the nonidealities derived from the circuit implementation of these chaotic systems have on their dynamics. The ergodic behavior of these systems is discussed in detail,...
In this paper an efficient and accurate method for computing the invariant measure of piecewise affine chaotic maps is proposed. As an application example, the method is used to evaluate for a chaos-based true random bit generator the robustness of the entropy with respect to small map parameters variations.
In this paper a novel family of maximum-period Nonlinear Congruential Generators (NLCGs) based on the digitized Renyi chaotic map is considered for the definition of hardware-efficient Pseudo Random Number Generators (PRNGs). In detail, a theoretical result is provided about the periodicity of the output sequences generated by the proposed NLCGs. Moreover, the distribution of the generated numbers...
In this paper, the guidelines to design a true random number generator (TRNG) circuit of uniform distributed numbers. The approach is proposed for a TRNG based on a one-dimensional piecewise-linear chaotic map and it is suitable for the development of integrated TRNG circuits. In particular, the proposed design strategy is based on a feedback control procedure that allows to dynamically change the...
In this paper the theoretical bases to design a true random bit generator (TRBG) circuit with a predefined minimum entropy are discussed. The approach is tailored to TRBGs based on a one-dimensional piecewise-linear chaotic map, and it is based on a feedback control procedure that allows to dynamically changing the system parameters. For this purpose, the procedure just exploits the TRBG output observation...
