The one-dimensional and two-dimensional integer tent maps are analyzed, and a three-dimensional dynamic integer tent map is proposed. Based on the extended dimension perturbations are applied to further extend the model accuracy. The dynamic behaviors of the integer tent map system under the disturbance mechanism, computational precision and spatial dimension are studied. The information entropy, mutual information, difference characteristic, Lyapunov exponent and randomness of the three-dimensional are simulated and analyzed. The results indicate that disturbance mechanism, computational precision and spatial dimension have a profound impact on the dynamic behaviors of the integer tent map. The three-dimensional integer tent map realized with high perturbation and high precision have excellent cryptographic performance.
