Characterisation of observability and controllability for nonuniformly sampled discrete systems
Amparo Fúster-Sabater, J. M. Guillén
A joint characterisation of the observability and controllability of a particular kind of discrete system has been developed. The key idea of the procedure can be reduced to a corr…
Questions of controllability and observability for nonuniformly sampled discrete systems
Amparo Fúster-Sabater, J. M. Guillén
A joint characterisation of the controllability and observability of a particular kind of discrete system has been developed. The key idea of the procedure can be reduced to a corr…
Simple Cellular Automata-Based Linear Models for the Shrinking Generator
Amparo Fúster-Sabater, Dolores de la Gu'\ia-Martínez
Structural properties of two well-known families of keystream generators, Shrinking Generators and Cellular Automata, have been analyzed. Emphasis is on the equivalence of the bina…
Correction to "Generalized Self-Shrinking Generator"
Amparo Fúster-Sabater
In this correspondence, it is given a correction to Theorem 4 in Y. Hu, and G. Xiao, "Generalized Self-Shrinking Generator," IEEE Transactions on Information Theory, vol. 50, No. 4…
Using Linear Difference Equations to Model Nonlinear Cryptographic Sequences
P. Caballero-Gil, A. Fúster-Sabater, M. E. Pazo-Robles
A new class of linear sequence generators based on cellular automata is here introduced in order to model several nonlinear keystream generators with practical applications in symm…
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…
