Abstract
- Here is a proposal of lossless dual-channel audio encryption scheme based on one-time keys, the novelty is to apply chaotic system with changeable multi-scroll to generate key stream to confuse and diffuse audio data, and the one-time keys, such as initial values of state variables, scroll number and initial iteration times of the chaotic system, are dependent on both external keys and hash value of the plain audio file, to make the chaotic trajectory more unpredictable. The algorithm owns large key space to make brute-force attack impossible. Statistical analysis demonstrates the effectiveness for fast audio encryption, and the scheme can also be applied in encrypting audio with more channels. [ABSTRACT FROM AUTHOR]
