Abstract:

Mathematics enables data encryption, information secrecy, and multimedia protection. Number theory supports chaos generators and pseudorandom number generators in increasing unpredictability in crucial ways. Using discrete, continuous, and fractional-order systems simplifies signal processing, edge detection, and secure storage of images, audio, and video. When implemented in hardware, these mathematical models provide fast, low-power data encryption and integrate effectively with video encoders for real-time data protection. Nonlinear dynamics and bifurcation theory enhance these techniques by introducing adaptable, model-based security features. Encryption that shifts systems from order to chaos is both flexible and highly sensitive to minor changes. Memristive and fractional-order systems expand the key space and strengthen resistance against analytical attacks. Bifurcation control models enable adjustment of chaotic behavior to optimize synchronization and encryption, supporting sophisticated encryption systems and safeguarding multimedia. This approach combines mathematical theory, nonlinear modeling, and hardware implementation to create an advanced information security framework that offers strong, flexible, and efficient data protection across multiple platforms.
