Abstract: A new cryptosystem based on multiple one-dimensional chaotic maps is proposed by utilizing the properties of chaotic map such as sensitivity to initial conditions and system parameters, and orbit uncertainty. The system parameters of chaotic maps and the using order of three one-dimensional maps are generated by using linear congruent generators. The initial value and iterative number of chaotic map and linear congruence generator (LCG) parameters are dynamically changed by output feedback. Simulation results and security analyses show that the proposed cryptosystem has large key space and high sensitivity to key and plaintext, and can resist the brute attack and statistical attack.
