Abstract
A novel cellular automata (CA) — two-dimensional controllable CA — is proposed in this paper. According to characteristics of two-dimensional controllable CA, a pseudo random generating method based on two-dimensional controllable CA with a trapezoidal structure is presented. Simulation demonstrates that pseudo random bit sequence generator based on the two-dimensional controllable CA with a trapezoidal structure is easily implemented, and can generate high speed bit sequence and excellent statistical properties. This novel CA is widely used in symmetrical cryptography.
