基于参数敏感性的MP3音频选择加密方案
MP3 Audio Selective Encryption Scheme Based on Data Sensitivity
【摘要】 提出一种与MP3音频编码过程相结合的快速音频加密方案,选择加密对安全性敏感的数据帧,并通过实验测试选择敏感参数类型,在帧内选择加密这些敏感参数。理论分析表明这种加密方案具有较高的安全性,实验结果表明加密效果好、运行速度快,能够满足无线网络传输和视频点播等应用中对实时性的要求。
【Abstract】 In this paper,a fast audio encryption scheme combining with MP3 audio encoding process is proposed,which encrypts data frames of high sensitivity,and encrypts sensitive data to decoding process in a frame that is obtained by testing experiment.Theoretic analysis shows that it’s of high security,and experiment result shows that it’s of high efficiency,which makes it suitable for many realtime applications,such as wireless multimedia transmission and video on demand, etc.
