Abstract: Pseudo random sequences have many applications in the field of cryptography,and it becomes one of the most important subjects in cryptography.One dimension additive extended non-uniform CA is constructed to solve the problem of large search space in cellular automata.The result shows that the generator outperforms some other one-dimensional CA generators,and it provides a constructive method for pseudo random sequences generator in cryptography.
