TL;DR: In this paper, the authors re-evaluate the security of a typical image-scrambling encryption algorithm (ISEA) using the internal correlation remaining in the cipher image, and demonstrate that some advanced multimedia processing techniques can facilitate the cryptanalysis of multimedia encryption algorithms.
Abstract: Position scrambling (permutation) is widely used in multimedia encryption schemes and some international encryption standards, such as the Data Encryption Standard and the Advanced Encryption Standard. In this article, the authors re-evaluate the security of a typical image-scrambling encryption algorithm (ISEA). Using the internal correlation remaining in the cipher image, they disclose important visual information of the corresponding plain image in a ciphertext-only attack scenario. Furthermore, they found that the real scrambling domain--the position-scrambling scope of ISEA's scrambled elements--can be used to support an efficient known or chosen-plaintext attack on it. Detailed experimental results have verified these points and demonstrate that some advanced multimedia processing techniques can facilitate the cryptanalysis of multimedia encryption algorithms.

TL;DR: A symmetric key image cryptosystem based on the piecewise linear map that can fight against the chosen/known plaintext attacks due to the using of plaintext-related scrambling and has many merits such as high encryption/decryption speed, large key space, strong key sensitivity, strong plaintext sensitivity, good statistical properties of cipher images, and large cipher-text information entropy.
Abstract: A symmetric key image cryptosystem based on the piecewise linear map is presented in this paper. In this cryptosystem, the encryption process and the decryption process are exactly same. They both include the same operations of plaintext-related scrambling once, diffusion twice and matrix rotating of 180 degrees four times. The length of secret key in the system is 64d where d is a positive integer. The proposed system can fight against the chosen/known plaintext attacks due to the using of plaintext-related scrambling. The simulate results and comparison analysis show that the proposed system has many merits such as high encryption/decryption speed, large key space, strong key sensitivity, strong plaintext sensitivity, strong cipher-text sensitivity, good statistical properties of cipher images, and large cipher-text information entropy. So the proposed system can be applied to actual communications.

TL;DR: A new digital image scrambling method based on Fibonacci numbers is presented, which can endure common image attacks, such as compression, noise and loss of data packet.
Abstract: A new digital image scrambling method based on Fibonacci numbers is presented. The uniformity and periodicity of the scrambling transformation are discussed. Our scrambling transformation has the following advantages: (1) encoding and decoding is very simple and they can be applied in real-time situations (2) the scrambling effect is very good, the information of the image is re-distributed randomly across the whole image; and (3) the method can endure common image attacks, such as compression, noise and loss of data packet.

TL;DR: This paper proposes a simple and effective digital video scrambling method which utilizes the intra block properties of a recent video coding technique, H.264.
Abstract: As the amount of digitalized contents increases rapidly, ‘security' necessarily arises as one of the most important issues. The main distribution channel of digital contents is Internet which is very easily accessible. Therefore content protection becomes a major issue as important as data coding techniques. In recent years, many developers have studied techniques that allow only authorized person to access contents. Among them, scrambling is one of well-known security techniques. In this paper, we propose a simple and effective digital video scrambling method which utilizes the intra block properties of a recent video coding technique, H.264. In addition to its simplicity, the proposed method does not cause bit rate increase after scrambling.
