Today I read a paper titled “Cryptanalysis of an image encryption scheme based on a new total shuffling algorithm”
The abstract is:
Chaotic systems have been broadly exploited through the last two decades to build encryption methods.
Recently, two new image encryption schemes have been proposed, where the encryption process involves a permutation operation and an XOR-like transformation of the shuffled pixels, which are controlled by three chaotic systems.
This paper discusses some defects of the schemes and how to break them with a chosen-plaintext attack.
