Digital video is one of the most popular multimedia data exchanged over the internet. Previous cryptography studies have focused on text data. The encryption algorithms developed for text data may not be suitable to multimedia applications because of large sizes of video. We present an algorithm in which a video file is encrypted by considering each frame as acolour image. Each video frame is broken down into RGB planes. Chaotic mapping algorithms are applied on all the planes of each frame, the temporal and horizontal domain of the video. For end-to-end authentication, semantically secure whirlpool hash has been used. Data integrity is verified using XOR hash which can detecttampering of data at any intermediate node. The algorithm was run on different videos, and satisfying results were obtained.
