摘要

基于混沌密码理论

提出一种新型加密方案.首先利用Arnold猫映射和3D-Lorenz混沌系统

通过改进算法产生混合混沌序列

再将其与明文信息运算产生密文信息

最后通过改进LSB信息隐藏算法将密文信息隐入音频载体.合法用户通过理想信道得到密钥和加密流程即可通过逆运算安全获得明文信息.经实验仿真证明

改进后的混沌序列完全满足各项密码学特性

整个系统能够安全、可靠地实现私密信息的网络传输.

Abstract

Based on the chaotic password theory

a new encryption method is brought forward.Firstly Arnolds cat mapping and 3D—Lorenz chaotic system are used by ameliorated algorithm to generate mixed chaotic sequences. Then the plaintext message is calculated with the sequences to generate the ciphertext message.Finally

the ciphertext is hided in audio carrier through improved LSB information hiding algorithm.The legal users can get the keys and the encryption workflow through the ideal channel.Then they can obtain the plaintext message in security by inverse operation.It is demonstrated by the simulation results that the improved chaotic sequences can completely meet the various cryptographic properties.And the whole system can realize the network transmission of private information safely and reliably.
