Internal symmetries of cellular automata via their polynomial representation.

A polynomial representation of elementary cellular automata (ECA) is used to give a complete characterization of the local internal symmetries of all ECA. It is also shown that the polynomial representation is a natural choice for the study of local internal transformations of all cellular automata with two symbols. This is achieved by proving that local internal transformations are simply expressed in this representation as sums of polynomials. (c) 1998 American Institute of Physics.

Synchronization of cellular automaton pairs.

The phenomenon of synchronization in pairs of cellular automata coupled in a driver-replica mode is studied. Necessary and sufficient conditions for synchronization in linear cellular automaton pairs are given. The couplings that make a pair synchronize are determined for all linear elementary cellular automata. (c) 1998 American Institute of Physics.

A cryptosystem based on cellular automata.

Cryptosystems for binary information are based on two primitives: an indexed family of permutations of binary words and a generator of pseudorandom sequences of indices. A very efficient implementation of the primitives is constructed using the phenomenon of synchronization in cellular automata. (c) 1998 American Institute of Physics.
