A color image cryptosystem based on dynamic DNA encryption and chaos
TL;DR: A four-wing hyperchaotic system is used to provide pseudo-random chaotic sequences, SHA 384 hash function of the plain image and external parameters are combined to compute its initial values, and one-time-pad encryption policy makes the proposed encryption effectively resist plaintext attacks.

A novel chaotic based image encryption using a hybrid model of deoxyribonucleic acid and cellular automata

A plaintext-related image encryption algorithm based on chaos
Yong Zhang,Yingjun Tang +1 more
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.

A symmetric image encryption scheme based on 3D chaotic cat maps
TL;DR: The two-dimensional chaotic cat map is generalized to 3D for designing a real-time secure symmetric encryption scheme that uses the 3D cat map to shuffle the positions of image pixels and uses another chaotic map to confuse the relationship between the cipher-image and the plain-image, thereby significantly increasing the resistance to statistical and differential attacks.

A block cipher based on a suitable use of the chaotic standard map
TL;DR: Experimental results show that the new block cipher based on the chaotic standard map has satisfactory security with a low cost, which makes it a potential candidate for encryption of multimedia data such as images, audios and even videos.

A general quantitative cryptanalysis of permutation-only multimedia ciphers against plaintext attacks
TL;DR: In this article, the performance of permutation-only multimedia ciphers against known/chosen-plaintext attacks was analyzed and it was shown that O(log"L(MN)) chosen plaintexts are sufficient to recover not less than (in an average sense) half of the plaintext.
