Breaking Points in Quartic Maps
M. Romera, G. Pastor, M. -F. Danca +3
Dynamical systems, whether continuous or discrete, are used by physicists in order to study non-linear phenomena. In the case of discrete dynamical systems, one of the most used is…
Finding Attractors of Continuous-Time Systems by Parameter Switching
M. -F. Danca, M. Romera, G. Pastor +1
The review presents a parameter switching algorithm and his applications which allows numerical approximation of any attractor of a class of continuous-time dynamical systems depen…
Security problems with a SC-CNN-based Chaotic Masking Secure Communication System
A. B. Orue, G. Alvarez, F. Montoya +1
This paper studies the security of a chaotic cryptosystem based on the Chua circuit and implemented with State Controlled Cellular Neural Networks. It is shown that the plaintext c…
A New Lorenz System Parameter Determination Method and Applications
A. Orue, G. Alvarez, G. Pastor +3
This paper describes how to determine the parameter values of the chaotic Lorenz system from one of its variables waveform. The geometrical properties of the system are used firstl…
Lorenz System Parameter Determination and Application to Break the Security of Two-channel Chaotic Cryptosystems
A. B. Orue, G. Alvarez, M. Romera +3
This paper describes how to determine the parameter values of the chaotic Lorenz system used in a two-channel cryptosystem. The geometrical properties of the Lorenz system are used…
Security analysis of communication system based on the synchronization of different order chaotic systems
G. Alvarez, L. Hernandez, J. Munoz +2
This work analyzes the security weakness of a recently proposed communication method based on chaotic modulation and masking using synchronization of two chaotic systems with diffe…
