A Maximum Entropy-Based Chaotic Time-Variant Fragile Watermarking Scheme for Image Tampering Detection

Entropy, 2013
The fragile watermarking technique is used to protect intellectual property rights while also providing security and rigorous protection. In order to protect the copyright of the creators, it can be implanted in some representative text or totem. Because

Weak noise approach to the logistic map

, 2004
Using a nonperturbative weak noise approach we investigate the interference of noise and chaos in simple 1D maps. We replace the noise-driven 1D map by an area-preserving 2D map modelling the Poincare sections of a conserved dynamical system with ...

Secure and Fast Image Encryption Algorithm Based on Modified Logistic Map

Inf.
In the past few decades, the transmission of data over an unsecure channel has resulted in an increased rate of hacking. The requirement to make multimedia data more secure is increasing day by day.

Security Improve in ZigBee Protocol Based on RSA Public Algorithm in WSN [PDF]

Engineering and Technology Journal, 2019
ZigBee is consuming low energy and providing the protection in Wireless Sensor Networks. ZigBee pro is supporting most applications. In spite of improved the security, ZigBee pro weak in key administration. In this paper, we depend on Logistic Map Diffie

Cryptanalysis of a family of self-synchronizing chaotic stream ciphers [PDF]

, 2009
Unimodal maps have been broadly used as a base of new encryption strategies. Recently, a stream cipher has been proposed in the literature, whose keystream is basically a symbolic sequence of the (one-parameter) logistic map or of the tent map.

Chaos of Exponential Logistic Map

Discrete Dynamics in Nature and Society
In this paper, chaos of a new exponential logistic map modulated by Gaussian function is investigated. Firstly, the stability of the fixed point is analyzed, and the occurrence of period doubling bifurcation in the system is verified theoretically ...

Bifurcations and transitions in the quasiperiodically driven logistic map [PDF]

, 2000
We discuss several bifurcation phenomena that occur in the quasiperiodically driven logistic map. This system can have strange nonchaotic attractors (SNAs) in addition to chaotic and regular attractors; on SNAs the dynamics is aperiodic, but the largest ...
