Chaotical PRNG based on composition of logistic and tent maps using deep-zoom
João Pedro do Valle Alvarenga, Jeaneth Machicao, Odemir Bruno
We proposed the deep zoom analysis of the composition of the logistic map and the tent map, which are well-known discrete unimodal chaotic maps. The deep zoom technique transforms…
Exploiting ergodicity of the logistic map using deep-zoom to improve security of chaos-based cryptosystems
Jeaneth Machicao, Marcela Alves, Murilo S. Baptista +1
This paper explores the deep-zoom properties of the chaotic k-logistic map, in order to propose an improved chaos-based cryptosystem. This map was shown to enhance the random featu…
A dynamical systems approach to the discrimination of the modes of operation of cryptographic systems
Jeaneth Machicao, Jan M. Baetens, Anderson G. Marco +2
Evidence of signatures associated with cryptographic modes of operation is established. Motivated by some analogies between cryptographic and dynamical systems, in particular with…
Fast, parallel and secure cryptography algorithm using Lorenz's attractor
Anderson Gonçalves Marco, Alexandre Souto Martinez, Odemir Martinez Bruno
A novel cryptography method based on the Lorenz's attractor chaotic system is presented. The proposed algorithm is secure and fast, making it practical for general use. We introduc…
