A Novel Comparison between Different Composite Chaotic Maps Applied on Sound Encryption

This paper presents three new composite chaotic maps used in a ciphering method for audio signals based on wavelet analysis. These new composite chaotic maps: Dyadic-Tent-Fibonacci (DTF), Tent-Fibonacci-Circle (TFC) and Tent-Fibonacci-Logistic (TFL) are compared in terms of encryption metrics (histograms, correlation, entropy, PSNR) with Tent-Logistic-Tent (TLT).
