Abstract Under Kirchhoff principle, the security property of digital chaotic encryption system is discussed using chosen-ciphertext attacking. The key of the encryption system can be got by chosen-ciphertext attacking. The digital chaotic encryption system based on digital filter does not have high privacy.

Key words： Chaos KirchhofF principle Chosen-ciphertext attack
