Security Bounds for the NIST Codebook-based Deterministic Random Bit Generator

Security Analysis of DRBG Using HMAC in NIST SP 800-90

HMAC DRBG is a deterministic random bit generator using HMAC specified in NIST SP 800-90. The document claims that HMAC DRBG is a pseudorandom bit generator if HMAC is a pseudorandom function. However, no proof is given in the document. This article provides a security analysis of HMAC DRBG and confirms the claim.

On the security of a double-scroll based "true" random bit generator

This paper is on the security of a “true” random bit generator (RBG) based on a double-scroll attractor. A clone system is proposed to analyze the security weaknesses of the RBG and its convergence is proved using master slave synchronization scheme. All secret parameters of the RBG are revealed where the only information available are the structure of the RBG and a scalar time series observed ...

A Pseudorandom Bit Generator based on Chaotic Coupled Map Lattices

In this paper, we discuss the properties of making a deterministic algorithm suitable to generate a pseudo random sequence of numbers: high value of Kolmogorov-Sinai entropy, high dimensionality of the parent dynamical system, and very large period of the generated sequence. We propose the chaotic coupled map lattices as a pseudo random number generator. We show what chaotic features of the cou...

A Pseudo Random Number Generator Based on Chaotic Billiards

The systems of chaotic billiards revealed a well developed chaotic behavior. Despite its good characteristics, these systems have not yet been applied to the cryptography; among the reasons is the difficulty of expressing the equation of particle motion in an explicit form. In this work, we took advantage the properties offered by the random walks and unpredictability of two particles moving in...
