TLDR
In this article, the authors demonstrate that this particular algorithm is vulnerable to a known-plaintext attack, and hence its use should be carefully considered, and discuss modifications that can make the algorithm resistant to our attack.Abstract:
One of the approaches to deliver real-time video encryption is to apply permutations to the bytes within a frame of a fully encoded MPEG stream as presented in [2]. We demonstrate that this particular algorithm is vulnerable to a known-plaintext attack, and hence its use should be carefully considered. We also discuss modifications that can make the algorithm resistant to our attack.read more

Proposed Video Encryption Algorithm v/s Other Existing Algorithms: A Comparative Study
TL;DR: In this paper, an innovative encryption algorithm for videos compressed using H.264 was proposed to safely exchange highly confidential videos, which shuffles the video frames along with the audio, and then AES is used to selectively encrypt the sensitive video codewords.

Methods for encrypting and decrypting MPEG video data efficiently
TL;DR: One of the methods is almost as e@cient as the existing video encoding and decoding process while providing considerable level of security without affeciing the quality of images when decrypted, and based on the wideiy used JPEG and MPEG standards.

Is MPEG encryption by using random list instead of zigzag order secure
TL;DR: The problems of the MPEG video encryption algorithm are discussed by using a random permutation list instead of a zigzag order within the MPEG compression process, showing that the encryption method causes a significant size increase of the video stream, hence defeats the purpose of compression.
