摘　　要：在Kerckhoff准则下,从选择密文攻击出发,探讨了基于混沌同步的混沌加密系统的安全性,并指出在选择密文攻击下可以获得加密系统的密钥.了基于超混沌的混沌加密系统和基于混沌的混合加密系统.结果表明,基于混沌同步的混沌加密系统不具有很高的安全性.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.
