Using hyper chaos in secure video transmission

This work presents a hardware implementation of hyper chaotic-based encryption algorithm utilized for video transmission in a secured way. Eight-dimensional hyper chaotic system is realized to generate a secret sequence used in both confusion and diffusion processes. The proposed scheme utilizes the hyper chaotic output to shuffle the pixel positions and change pixel values for each video frame in order to obtain totally changed video frames. The proposed system is experimentally verified on hardware module (NI-MyRIO) based on field programmable gate array (FPGA) and ARM processor. The encrypted video frames are sent to the receiver side through wireless fidelity (WiFi), the receiver has the same hyper chaotic generator with identical initial conditions and control parameters. The security analysis will be investigated to evaluate the performance of the proposed system.
