Modelling Nonlinear Sequence Generators in terms of Linear Cellular Automata
Amparo Fúster-Sabater, Dolores de la Guía-Martínez
In this work, a wide family of LFSR-based sequence generators, the so-called Clock-Controlled Shrinking Generators (CCSGs), has been analyzed and identified with a subset of linear…
A Simple Computational Model for Acceptance/Rejection of Binary Sequence Generators
Amparo Fúster-Sabater, Pedro García-Mochales
A simple binary model to compute the degree of balancedness in the output sequence of LFSR-combinational generators has been developed. The computational method is based exclusivel…
On the Use of Cellular Automata in Symmetric Cryptography
Amparo Fuster-Sabater, Pino Caballero-Gil
In this work, pseudorandom sequence generators based on finite fields have been analyzed from the point of view of their cryptographic application. In fact, a class of nonlinear se…
A Basic Framework for the Cryptanalysis of Digital Chaos-Based Cryptography
David Arroyo, Gonzalo Alvarez, Veronica Fernandez
Chaotic cryptography is based on the properties of chaos as source of entropy. Many different schemes have been proposed to take advantage of those properties and to design new str…
