dc.descriptionThe combinative applications of one-way coupled map lattice (OCML) and some simple algebraic operations have demonstrated to be able to construct the best known chaotic cryptosystem with high practical security, fast encryption speed, and excellent robustness against channel noise. In this paper, we propose a differential-like chosen cipher attack to break the prototypical system cooperating with INT and MOD operations. This cryptographic method exploits the weakness that the high-dimensional cryptosystem degenerates to be one-dimensional under constant driving, therefore, is no more sensitive to the slight perturbation on the driving after convergence. The experimental results show that this method can successfully extract the key within just hundreds of iterations. To the best of our knowledge, it is the first time to present successful cryptanalysis on such a cryptosystem. we also make some suggestions to improve the security in future versions.
