摘要

The enormous growth and usage of digital multimedia information through communication networks, including image and video files, have increased the demand for safeguarding such digital information during transferring processes. Video ciphering is widely employed to protect private video content from unauthorized access. Chaos-based ciphering algorithms have shown an increasingly significant role in modern video cryptography compared to classical approaches. Therefore, this article proposes a video ciphering technique based on a new one-dimensional chaotic map. The presented chaotic map integrates the Sine and Cubic maps to form a new chaotic system called One-Dimension-Combined-Sine-Cubic-Map (1D-CSCM). Furthermore, the introduced 1D-CSCM system is utilized to develop a video ciphering mechanism. First, the input color video file is separated into RGB frames, and the extracted frames are scrambled using the first sequence generated by the suggested map. The scrambled frames are then partitioned into red, green, and blue channels; this process is followed by channel scrambling using the second sequence produced by the 1D-CSCM. The subsequent step involves dividing the shuffled channels into \(8\times 8\) blocks, the resulting blocks as well as pixels inside each block are permutated by applying the third and fourth chaotic sequences generated by the new map, respectively. The final ciphering stage involves implementing the diffusion process on the shuffled pixels in each block by employing the fifth sequence produced by the designed map. Extensive experimental results confirm that the proposed video cryptosystem demonstrates excellent performance in terms of security and efficiency.
