Known-Plaintext Attack Against a Permutation Based Video

نویسنده

Adam J. Slagell

چکیده

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.

A general quantitative cryptanalysis of permutation-only multimedia ciphers against plaintext attacks

In recent years secret permutations have been widely used for protecting different types of multimedia data, including speech files, digital images and videos. Based on a general model of permutation-only multimedia ciphers, this paper performs a quantitative cryptanalysis on the performance of these kind of ciphers against plaintext attacks. When the plaintext is of size M ×N and with L differ...

Cracking a hierarchical chaotic image encryption algorithm based on permutation

In year 2000, an efficient hierarchical chaotic image encryption (HCIE) algorithm was proposed, which divides a plain-image of size M×N with T possible value levels into K blocks of the same size and then operates position permutation on two levels: intra-block and inter-block. As a typical position permutation-only encryption algorithm, it has received intensive attention. The present paper an...

Is Mpeg Encryption by Using Random List Instead of Zigzag Order Secure?

This paper discusses the problems of the MPEG video encryption algorithm by using random permutation list instead of zigzag order within the MPEG compression process. We show that 1) the en-cryption method causes a signiicant size increase of the MPEG video stream, hence defeats the purpose of compression, and 2) the encryption method can not withstand the known-plaintext attack, therefore, sho...

Cryptanalysis 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 ...
