    A Novel Digital Audio Encryption Algorithm Using Three Hyperchaotic Rabinovich System Generators by Ameer K. Jawad, Gholamreza Karimi, Mazdak Radmelkshahi

    Published 2024-12-01
    “…Three hyperchaotic systems allow digital audio signal randomized encryption. The first system generates chaotic random integer numbers as keys, the second selects non-sequential indices to increase unpredictability, and the third randomly samples the digital audio signal and encrypts it through XOR operations with a selected key, making it harder for intruders to learn the encryption pattern. …”
