Optical Bit-Plane-Based 3D-JST Cryptography Algorithm With Cascaded 2D-FrFT Encryption for Efficient and Secure HEVC Communication

The rapid growth of multimedia communication systems has expanded the High-Efficiency Video Coding (HEVC) security applications precipitously. Therefore, there is an urgent, elevated need to protect and secure HEVC content during streaming over insecure channels ensure privacy data against intruders attackers. This paper introduces optical cipher algorithm based on bit-plane 3D-JST (Three-Dimensional Jigsaw Transform) multistage 2D-FrFT (Two-Dimensional Fractional Fourier encryption. main advantage employing its unitary transform that inverse used reorganize frame-blocks in indiscriminately way. proposed embraces cascaded encryption domain using a single arbitrary phase code; be executed all optically with lone lens. suggested utilizes two stages distinct kernels mutually dimensions separated by code. A foregoing permutation stage conducted input frames before processes accomplish high robustness level. To validate efficacy cryptography for streaming, comprehensive evaluation framework been introduced followed (a) test streams different statistical cryptographic metrics, (b) compare recent related works whether optical-based or digital-based algorithms (c) study impact attacks performance. results show efficient outperforms conventional terms examined metrics.
