Efficient Signature Scheme Using Extended Chaotic Maps for Medical Imaging Records
Proceedings of the 4th International Conference on Medical and Health Informatics, 2020Digital security issues such as medical records, diagnostic certificates, medical images, etc. in the medical community have gradually been paid attention to. Nowadays, encrypting and signing electronic medical records including medical imaging records still have to rely on time-consuming exponential computations.

A Chaotic Digital Communication System Using an Extended Bernoulli Map
2006 International Symposium on Intelligent Signal Processing and Communications, 2006This paper presents a novel chaotic digital communication system that uses an extended Bernoulli map (EBM). We use the discontinuous point of EBM as information carrier. Chaotic signals generated with EBM in which the discontinuous points are modulated by the information to be transmitted are sent to the receiver.

An extended image encryption using chaotic coupled map and S-box transformation
Nonlinear Dynamics, 2014This manuscript is about a modified image encryption algorithm based on coupled map lattices and substitution box transformation. The places of the pixels of image are mix up by using chaotic tent map and after that employing delayed coupled map lattices and S-box transformation to puzzle the association between the original image and the encrypted ...

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2016
Global bifurcations include sudden changes in chaotic sets due to crises. There are three types of crises defined by Grebogi et al. [Physica D 7, 181 (1983)]: boundary crisis, interior crisis, and metamorphosis. In this paper, by means of the extended generalized cell mapping (EGCM), boundary and interior crises of a fractional-order Duffing system are
