Enhanced Video Encryption Technique Using Substitution Boxes and Spatial Filtering for Robust Data Security

Video encryption is a technique used to protect video data, which has become increasingly crucial due to the rise of intruders attempting to steal private information.Ensuring the protection of sensitive data during transmission is of paramount importance across various domains.Current encryption algorithms often struggle to balance security and efficiency, resulting in compromises on one or both aspects.To address this issue, we propose an enhanced video encryption technique utilizing substitution boxes (S-boxes) and spatial filtering.The proposed method avoids the overhead caused by the repetition of chaotic sequences, leading to improved encryption efficiency.Authentic video frames, which are unaltered, are converted into three-dimensional videos.Spatial permutations, spatial filtering, and image superposition are applied in three rounds along the x, y, and z axes.S-boxes are generated to provide an additional layer of security.Throughout the process, pixels in the video frames are randomly switched to ensure the final encrypted video is secure.Compared to currently available algorithms, the results of our analysis demonstrate that the proposed method achieves superior levels of both security and efficiency, making it well-suited for ensuring robust data security during transmission.
