Because of the COVID-19 pandemic, most of the tasks have shifted to an online platform.
Sectors such as e-commerce, sensitive multi-media transfer, online banking have …

To ensure the security transmission of audio signals in instant messaging tools, a chaos-
based dual-channel one-time one-key audio encryption scheme was proposed. First, a non …

The surge in online activities has led to the increasing popularity of sharing video data
across diverse applications, including online education tutorials, social networking, video …

A significant problem facing cybersecurity is that most client/server identity authentication
schemes depend on computational complexity which is recently challenged by the super …

In the recent years, significant research interest has been devoted in the modelling and
applications of chaotic systems with stable equilibria. In this research study, we propose a …

Biometric authentication systems have gained significant popularity in recent years due to
their high level of security and convenience. Cancelable biometrics is a promising area of …

This work aims to improves the chaotic behavior of classical logistic chaotic system for voice
encryption. In this study, the classical chaotic system was enhanced. This enhanced map …

In this work, we have proposed an audio encryption method. The proposed method is audio
signal sensitive as the hash value of the given signal is computed using SHA3-512, which …

I would like to express my deep and sincere appreciation to my supervisor Dr Wassim
Alexan, who has helped me in writing my thesis. He has always supported me in any way he …

Traditional encryption algorithms like DES suffer from the issue of key length (128 bits to 256
bits) and the inconvenience of memorization. Users typically store keys in a file or device, or …
