Recently, two chaotic image encryption schemes have been proposed, in which shuffling the positions and changing the grey values of image pixels are combined. This paper provides the chosen plaintext attack to recover the corresponding plaintext of a

Chaotic maps can be used in constructing hash function because of their properties, such as parameter-sensitivity and random-similarity. Many algorithms have been proposed for chaos-based one-way hash function. However, how to map bit strings into de

In this paper, a novel image encryption scheme based on chaotic maps is proposed. By combining XOR operations and circular bit shift operation, the security of this encryption algorithm is enhanced effectively. Two chaotic maps are adopted in the pro
