Pseudorandom number generation (PRNG) is a key element in hardware security platforms like fieldprogrammable gate array FPGA circuits. In this article, 18 PRNGs belonging in 4 families (xorshift, LFSR, TGFSR, and LCG) are physically implemented in a FPGA and compared in terms of area, throughput, and statistical tests. Two flows of conception are used for Register Transfer Level (RTL) and High-...

Abstract Security is a key factor in today’s fast communicating world. Many cryptographic algorithms are tested and put into use efficiently. Random numbers used diverse forms like nonces, secret key, initialization vector, etc. They find place encryption, digital signature, hashing algorithms. A deterministic takes an intial seed value as input produces pseudo random with falsely induced rando...

This paper targets to search so-called good generators by doing a brief survey over the developed in history of pseudo-random number (PRNGs), verify their claims and rank them based on strong empirical tests same platforms. To do this, genre PRNGs so far are explored classified into three groups — linear congruential generator based, feedback shift register cellular automata based. From each gr...

Guaranteeing security in information exchange is a challenge public networks, such as the highly popular application layer Message Queue Telemetry Transport (MQTT) protocol. On one hand, chaos generators have shown their usefulness masking data that can be recovered while having appropriate binary string. Privacy then accomplished by implementing synchronization techniques to connect transmitte...

Chaotic systems are widely used in image encryption due to their sensitivity initial values, ergodicity, and other properties; many algorithms based on chaotic have been studied the past few years. To obtain a more secure algorithm, this work firstly proposes new two-dimensional discrete hyperchaotic map, which has wider continuous interval, larger Lyapunov exponents passed all NIST part of Tes...

Abstract Theoretically, any chaotic system or map has ideal complex dynamics. However, because of the finite precision simulation software and digital devices during implementation, systems often undergo dynamical degradation, which hinders further application in many fields. Therefore this paper, method based on perturbation Unscented Kalman Filter (UKF) theory is designed to counteract degrad...
