ABSTRACT The work described in this paper can be interpreted as an application of the
order patterns of symbolic dynamics when dealing with unimodal maps.
Specifically, it is shown how Gray codes can be used to estimate the
probability distribution functions (PDFs) of the order patterns of parametric
unimodal maps. Furthermore, these PDFs depend on the value of the parameter,
what eventually provides a handle to estimate the parameter value from symbolic
sequences (in form of Gray codes), even when the critical point depends on the
parameter.

##### Article: A family of multimodal dynamic maps
[Hide abstract]
ABSTRACT: We introduce a family of multimodal logistic maps with a single parameter. The maps domain is partitioned in subdomains according to the maximal number of modals to be generated and each subdomain contains one logistic map. The number of members of a family is equal to the maximal number of modals. Bifurcation diagrams and basins of attraction of fixed points are constructed for the family of chaotic logistic maps.Research highlights► A family of chaotic multimodal logistic maps is proposed and basins of attraction of each fixed point of the family are constructed in terms of the bifurcation parameter. ► The attractor domain in the parameter space increases as a number of modals grows up. ► Each multimodal logistic map displays a stretching-and-folding structure and its bifurcation diagrams reproduce scaled bifurcations of the classical logistic map.

##### Article: On the inadequacy of unimodal maps for cryptographic applications
[Hide abstract]
ABSTRACT: The security of chaos-based cryptosystems is closely related to the possibility of recovering control parameters and/or initial conditions from partial information on the associated chaotic orbits. In this paper we analyze this possibility for the case of unimodal maps. We show a meaningful set of contexts where the dynamics of unimodal maps can be reconstructed, which means a relevant reduction of the scope where this kind of chaotic maps can be applied to build up new encryption procedures.
