摘　　要：提出了一种使用Lorenz混沌系统,Logistic混沌系统和MP3编码过程相结合的音频加密方法。首先由Lorenz混沌系统与Logistic混沌系统产生一张混沌表,根据混沌表生成的混沌序列作为加密序列。加密序列将MP3数据帧中的比例因子和霍夫曼码加密,这种加密方法不仅保证了安全性,同时也提高了加密的效率。In this paper, an audio encryption scheme combining with Lorenz chaotic system, Logistic chaotic system and MP3 audio encoding process is proposed. First the Lorenz chaotic system and Logistic chaotic system to produce a chaotic list, according to the table to generate chaos sequence of chaotic sequence as encryption. Encryption MP3 scaling factor and Huffman code of the data frames by encrypting sequence, this scheme not only ensures the security but also improve the efficiency of the encryption.
