Article: Chaos-based block cipher for video stream encryption Journal: International Journal of Internet Technology and Secured Transactions (IJITST) 2025 Vol.13 No.7 pp.1 - 21 Abstract: The growth of multimedia content in the digital era necessitates efficient and secure video encryption methods. Traditional algorithms like AES and DES often struggle with the computational demands of video data, especially in MP4 container formats. This paper proposes a novel chaos-based block cipher designed specifically for MP4 video encryption. Unlike prior methods relying on one-dimensional chaotic functions, this algorithm employs Arnold's cat map for robust pixel permutation and piecewise linear chaotic maps for diffusion, integrated within a multi-processing architecture. This approach ensures high security with low pixel correlation, high key sensitivity, and resistance to statistical and differential attacks. Our method balances security and efficiency, making it ideal for resource-constrained multimedia applications. Inderscience Publishers - linking academia, business and industry through research
