Abstract
This paper studies the security of a recently-proposed chaos-based
image encryption scheme, and points out the following problems: 1)
there exist a number of invalid keys and weak keys, and some keys
are partially equivalent for encryption/decryption; 2) given one
chosen plain-image, a subkey
