1. A new cryptography method based on the pre-image calculus of chaotic, non-homogeneous and non-additive cellular automata / Um novo método criptográfico baseado no cálculo de pré-imagens de autômatos celulares caóticos, não-homogêneos e não-aditivos
A new cryptographic method based on cellular automata (CA) has been investigated. In this method, the ciphering process is performed by preimages computation while deciphering is performed by CA temporal evolution. The preimages calculus is able to be used in a cryptographic system only if any arbitrary CA lattice has at least one preimage. In a previous met
