Chosen ciphertext attack on chaos communication based on chaotic synchronization

摘要

In this brief, we analyze the secure property of a chaos-communication system based on chaotic synchronization using the chosen-ciphertext attack under the Kerckhoff principle. We point out that a secure communication system based on chaotic synchronization is not highly secure. We can resolve the parameters (keys) of the secure communication system by the chosen-ciphertext attack.
