Query: Cryptanalysis of an image encryption scheme based on a new total
  shuffling algorithm   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.
