Security Property of Chaotic Encryption System Based on Chaotic Synchronization

The security property of chaotic encryption system based on chaotic synchronization from chosenciphertext attacking under Kerckhoff principles was discussed. The key of the receiver can be got by chosenciphertext attacking. It analyzed a kind of encryption system based on hyperchaos and the hybrid chaotic communication scheme using encryption and synchronization chaos. The result indicates that the encryption system based on chaotic synchronization does not have high privacy.
