چکیده

One of the widely-used ways in chaos-based cryptography to generate pseudo-random sequences is use least significant bits or digits finite-precision numbers defined by chaotic orbits. In this study, we show that results obtained using such an approach are very prone rounding errors and discretization effects. Thus, it appears generated close random even when parameters correspond non-chaotic oscillations. confirm actual source properties a binary representation can not be chaos, but computer simulation. We propose technique for determining maximum number used as output sequence generator including algorithms. The considered involves evaluating difference two points different numerical methods same order accuracy. Experimental estimation significantly increase performance existing generators. reconsider improve cryptographic

Chaos-based Pseudo-Random Number Generators and Chip Implementation

Cryptography as an ancient subject is endowed with new vigor by chaos theory. Cryptography protects the security of today’s ubiquitous Internet communication, which as an open network is vulnerable to attack. In this paper, chaos-based cryptography is surveyed with focus on designing chaotic pseudo-random number generators (CPRNGs) for stream cipher and their chip implementation. The properties...

Pseudo-Random Number Generators

The first option here is not easy. Some pieces of data of this kind exist, for example from the decay of radioactive elements, but generally generation is slow and you cannot get the quantity of random numbers you require for modern applications. The second option here is what I’ll talk about today. Algorithms of this type are called “PseudoRandom Number Generators” (PRNGs). Many bad algorithms...

Sponge-Based Pseudo-Random Number Generators

This paper proposes a new construction for the generation of pseudo-random numbers. The construction is based on sponge functions and is suitable for embedded security devices as it requires few resources. We propose a model for such generators and explain how to define one on top of a sponge function. The construction is a novel way to use a sponge function, and inputs and outputs blocks in a ...
