Cryptanalysis of Video Encryption Algorithms

چکیده
Content security is an important issue in multimedia applications. In this paper we perform a cryptanalysis of several encryption algorithms that have been proposed to protect the privacy of MPEG video streams. In particular, we analyze the encryption based on permuting the Huffman codeword list, and two selective encryption algorithms VEA and MVEA. For the convenience of the reader, we provide a simple overview of MPEG encoding, and we include all analyzed algorithms and their characteristics.

A Performance Survey of Meta-Heuristic And Brute-Force Search Algorithms to Cryptanalysis The SDES Encryption Algorithm
For many years, cryptanalysis has been considered as an attractive topic in jeopardizing the security and resistance of an encryption algorithm. The SDES encryption algorithm is a symmetric cryptography algorithm that performs a cryptographic operation using a crypt key. In the world of encryption, there are many search algorithms to cryptanalysis. In these researches, brute force attack algori...
متن کاملCryptanalysis of GSM encryption algorithm A5/1
The A5/1 algorithm is one of the most famous stream cipher algorithms used for over-the-air communication privacy in GSM. The purpose of this paper is to analyze several weaknesses of A5/1, including an improvement to an attack and investigation of the A5/1 state transition. Biham and Dunkelman proposed an attack on A5/1 with a time and data complexity of 239.91and 221.1, ...
متن کاملArtemia: a family of provably secure authenticated encryption schemes
Authenticated encryption schemes establish both privacy and authenticity. This paper specifies a family of the dedicated authenticated encryption schemes, Artemia. It is an online nonce-based authenticated encryption scheme which supports the associated data. Artemia uses the permutation based mode, JHAE, that is provably secure in the ideal permutation model. The scheme does not require the in...
متن کاملCryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables
This paper studies the security of a recentlyproposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack and known-plaintext attack; 2) it is possible to decrypt a cipher-video with a partiallyknown key, thus dramatically reducing the complexity of ...
متن کاملConfidentiality of a selectively encrypted H.264 coded video bit-stream
It is an assumption that selective encryption does not strongly protect confidentiality owing to the partial visibility of some video data. This is because, though encryption keys may be difficult to derive, an enhanced version of selectively encrypted video sequence might be found from knowledge of the unencrypted parts of the sequence. An efficient selective encryption method for syntax eleme...
