A systematic methodology is proposed for a chaotic map-based real-time video encryption and decryption system with Advanced RISC Machine (ARM)-embedded hardware implementation. According to the anti-control principle of dynamical systems, first, an 8-dimensional discrete-time chaotic map-based system is constructed, which possesses the required property of 1-1 surjection in the integer range [0, N − 1], where N denotes the number of frame pixels, suitable for position scrambling of each video frame. Then, an 8-D discrete-time hyper-chaotic system is designed for encryption-decryption of RGB tricolor pixel values. Based on the ARM-embedded platform super4412 model with Cortex-A9 processor, together with the standard QT cross-platform, an integrated chaotic map-based real-time secure video communication system is designed, implemented and evaluated. In addition, the security performance of the designed system is tested by using criteria from the NIST statistical test suite. The main feature of this method is that, both scrambling-antiscrambling of RGB tricolor pixel positions and encryption-decryption of pixel values are realized at the same time for enhancing the security. As is well known, compared with numerical simulations, hardware implementation for such a secure video communication system is very difficult to achieve, but it was successfully implemented and tested in a real world network environment by us. Both theoretical analysis and experimental results validate the feasibility and real-time performance of the new secure video communication system.
