Aiming at the defect that the decoder does not need to be initialized before decoding and the attackers can easily reconstruct the decoder structure, a new method of codec improvement is proposed. The improved decoder can restore the original information sequence correctly only when the initial state of the coder and decoder is the same. The simulation results show that the improved chaotic codec structure has better confidentiality than the original structure.
