ABSTRACT The usage of multimedia data has grown exponentially over the past few decades, with a significant portion of its content in the form of images and videos, which are transmitted across various public networks. As the prevalence of video content continues to rise, so does the critical need for enhanced data security. Recently, several techniques have been proposed to create efficient data security procedures, focusing on security, robustness and computational complexity. This paper proposes a secure and robust video encryption technique based on the concepts of confusion and diffusion. During the confusion phase, horizontal and vertical permutations of pixel values are performed using a permutation box and then pixel values are substituted based on a lookup table. In the diffusion phase, the pixel values of the first frame are XORed with a defined box, and then, sequentially, the pixel values in the remaining frames are XORed using the previous frame as a reference. Each stage requires keys for processing that are generated by three different chaotic logistic maps, which successfully passed the NIST test. These numbers are then XORed to implement a multi‐chaotic logistic map effectively. Simulation metrics, including entropy, correlation, NPCR, UACI, and so forth demonstrate the strength of the proposed method. The result analysis also states that the proposed methodology performs well in terms of Quantitative Security Analysis Correlation Analysis 0.0017, Entropy Analysis 7.99, Peak Signal to Noise Ratio 7.898, Mean Square Error 10549.37, Structural Similarity Index (0.0075), Key Space Analysis (), Differential Attack Analysis (Number of Pixel Change Rate 99.61 and Unified Average Change Intensity 33.46), Robustness Analysis (Salt and Paper Noise (pass), Gaussian Noise (pass), Occlusion Attack (pass) and Execution Time Analysis θ ( n )).
