摘要：

Alexopoulos, Bourbakis and Ioannou proposed two cryptographic schemes for encrypting 2-D gray scale images by using a large family of fractals respectively. Their schemes are based on a transposition of the image elements. However, their schemes will be vulnerable in case that they employ the unique key in their proposed system. In this paper, we show that their transposition encryptions can easily be broken with a pair of plain-image and cipher-sequential data. Meanwhile, we offer some suggestions for 2-D image transposition encryption.
