Video Encryption Algorithm and Key Management using Perfect Shuffle

Advancements in networking technologies like cloud computing have popularized applications like, Video-On Demand (VOD), video conferencing, pay-per-view, video broadcast, etc, in all such applications, confidentiality of the video data during transmission in network and during storage is extremely important. This necessitates secure video encryption algorithms suitable for multimedia application because of the large data size and real time constraint. Conventional encryption algorithms are designed for generic data, and as such, it does not support many specific video application requirements. In the paper we propose a computationally efficient and secure video encryption algorithm that makes encryption feasible for real-time applications without heavy computational overhead and reduces key management by utilizing block shuffling technique. Block Shuffling based video encryption with Faro IN OUT Shuffle and rotation, i.e., first image is rotated by an angle then key is generated based Block size using Faro IN OUT perfect shuffle which is a perfect shuffling algorithm which is isomorphic to random permutation. we will show that our proposed method provide more scrambling of image then random permutation and no need to maintain long key file.
