Abstract
Synchronization of 4-D nonlinear fractional order hyperchaotic system with external disturbance is important models for encryption and decryption technique. In this paper, the fractional order 0 < alpha <= 1 is consider to establish finite-time control for synchronization of sender and receiver system. An audio encryption and decryption algorithms are investigated based on converting an audio data samples into image data. A random mask generated from chaotic mask is used to encrypt and decrypt the audio signals. The path of error system of fractional order hyperchaotic system is shown to be highly better than the classical one. Further, high level security of the proposed work is entrusted or assured by analyzing various metrics including MSE, PSNR, SSIM, NPCR and SNR along with numerical simulations.
