A Novel Lightweight Encryption Scheme for Multimedia Data Special focus on Video Processing through Chaos Based Transformations

The usage of Multimedia data has increased by many folds in recent years. And with so many different types of devices available to access the data, it becomes imperative to protect its sanctity. In this paper, a novel lightweight encryption scheme using a secret key has been proposed for multimedia data especially Videos. Chaos based maps has been used to provide an apt level of confusion and diffusion process at different levels of Video Processing. Proposed technique has a high encryption rate and performs well even with the videos with excessive redundant data. Security Analysis has been performed to validate the high security features against different types of Statistical and Differential attacks and helps to prove the effectiveness of proposed system.
