The output sequences are written as solutions of linear difference equations, and three basic properties (period, linear complexity and number of different output sequences) are analyzed."eninfo:eu-repo/semantics/embargoedAccessCRIPTOGRAFIAECUACIONES EN DIFERENCIASUsing linear difference equations to model nonlinear cryptographic sequencesArtículos de Publicaciones Periódicas
