An audio encryption scheme based on Fast Walsh Hadamard Transform and mixed chaotic keystreams
This paper introduces an audio encryption algorithm based on permutation of audio samples using discrete modified Henon map followed by substitution operation with keystream generated from the modified Lorenz-Hyperchaotic system. In this work, the audio file is initially compressed by Fast Walsh Had...
