基于Arnold变换和DRPE技术的数字音频信号加密方案
|
摘要
针对音频信号文件冗余度高、数据量大、相关性强,以及传统加密方法不能满足当前高效实时安全性的需要,本文应用图像加密的思想,提出将一维数字音频信号转化二维"声图"信息,并借助Arnold变换和DRPE技术对其进行双重加密,达到即使部分密文数据缺失仍然能够恢复音频信号,并且又可以破坏原始信号数据间相关性的目的;此外,DRPE采用加密无理数序列构建随机相位板,增加了密钥空间,进一步提高了加密信息的安全性,同时,这种加密能够通过图形比较更直观地评判加密效果,避免了对音频解密信号质量评判时存在的主观方法受人为因素影响大和客观方法复杂且不能完全反映听觉效果的缺陷。实验结果证明,该加密方案对密文信息剪切、加噪、滤波等攻击具有很强的鲁棒性。
In view of the high redundancy of audio signal files,the large amount of data,and the strong correlation,traditional encryption methods cannot meet the needs of the current high-efficiency real-time security. In this paper,the idea of image encryption is applied to propose the conversion of one-dimensional digital audio signals into two-dimensional"sound map"information. With the help of Arnold transform and DRPE technology,it is double-encrypted to achieve the purpose of restoring audio signals even if part of the cipher text data is missing,and it can also destroy the correlation between the original signal data. In addition,DRPE encryption uses a random phase plate constructed by irrational number sequences to increase the key space and further improve the security of encrypted information. At the same time,this kind of encryption can judge the effect of encryption more intuitively,and avoid the subjective method that exists when evaluating the quality of audio decryption signal is greatly influenced by human factors. The objective method is complex and cannot fully reflect the defects of the auditory effect. The experimental results show that the encryption method is robust to clipping,noise,filtering and other attacks of cipher text information.
