Abstract

The massive development of IoT, Big Data and other technologies has led to security concerns with respect to data protection. It has become imperative to develop solutions to protect our data, such as images, texts, and audios from unauthorized access. This work presents an encrypted image transmission scheme based on a chaotic dynamic configuration of two synchronized spherical chaotic attractors of 3 dimension in a parent-child topology. We synchronized the future evolution of the chaotic systems starting with different initial conditions using the Hamiltonian observer-based approach and then utilized the resulting phase space points as the pseudo-random numbers for securing image transmitted through the communication channel. The scheme designed is realized and implemented on the Multiprocessor System-on- Chip (MPSoC) platform by harnessing the easy and synthesizable programming features of Python with MPSoC. The image is transmitted through the state variables x1, x2, and x3, and analyzed using the two statistical techniques namely, information entropy and correlation analysis where the result shows the full recovery of the image that was transmitted through the state variables.
