Two-dimensional one-way coupled map lattices are used for cryptograph wheremultiple space units produce chaotic outputs in parallel. One of the outputsplays the role of driving for synchronization of the decryption system whilethe others perform the function of information encoding. With this separationof functions the receiver can establish a self-checking and self-correctionmechanism, and enjoys the advantages of both synchronous and self-synchronizingschemes. A comparison between the present system with the system of AdvancedEncryption Standard, AES, is presented in the aspect of channel noiseinfluence. Numerical investigations show that our system is much stronger thanAES against channel noise perturbations, and thus can be better used for securecommunications with large noise channel exists in open channels, e.g.,mobile-phone secure communications.
