AbstractIn this paper, a method of generating cryptographic sequences based on discrete linear chaotic cellular automata is presented. The importance of the proposal is due to the fact that such cryptographic sequences are also output sequences of a nonlinear keystream generator known as Generalized Self-Shrinking Generator. Moreover, such a keystream generator is still considered secure in symmetric cryptography. Thus, it must be noticed that the linearity of the proposed chaotic model based on additive one-dimensional cellular automata might be used to mount a cryptanalytic attack against such a nonlinear generator.
