Blockchain driven medical image encryption employing chaotic tent map in cloud computing [PDF]

Scientific Reports
Data security during transmission over public networks has become a key concern in an era of rapid digitization. Image data is especially vulnerable since it can be stored or transferred using public cloud services, making it open to illegal access ...

Parrondo’s Paradox for Tent Maps [PDF]

Axioms, 2021
In this paper, we study the dynamic Parrondo’s paradox for the well-known family of tent maps. We prove that this paradox is impossible when we consider piecewise linear maps with constant slope.

Cryptographic Grade Chaotic Random Number Generator Based on Tent-Map

Journal of Sensor and Actuator Networks, 2023
In recent years, there has been an increasing interest in employing chaotic-based random number generators for cryptographic purposes. However, many of these generators produce sequences that lack the necessary strength for cryptographic systems, such as

Fractal Tent Map with Application to Surrogate Testing

Fractal and Fractional
Discrete chaotic maps are a mathematical basis for many useful applications. One of the most common is chaos-based pseudorandom number generators (PRNGs), which should be computationally cheap and controllable and possess necessary statistical properties,

Design of Discretized Tent Map

The Journal of the Korea Contents Association, 2008
To present the design procedure of discretized 8-bit tent map executing the transformation of tent function which is one of the chaotic functions, first, the truth table of discretized tent map was written, and then according to the simplified Boolean algebra equations obtained from the truth table, the discretized map is implemented with the exclusive

The Unreasonable Effectiveness of the Chaotic Tent Map in Engineering Applications

Chaos Theory and Applications, 2022
From decimal expansion of real numbers to complex behaviour in physical, biological and human-made systems, deterministic chaos is ubiquitous. One of the simplest examples of a nonlinear dynamical system that exhibits chaos is the well known 1 ...
