Abstract

Recently, a novel image encryption scheme using progressive cellular automata (CA) substitution and SCAN was proposed. This paper analyzes the security of the scheme and reports the following problems: 1) the scheme is not sensitive to the changes of plain-images; 2) the scheme is not sensitive to the changes of the key streams generated by CA; 3) there are some problems about the secret key of the scheme; 4) the scheme can be broken with no more than chosen-images when the two basic parts of the scheme are not iterated, where MN is the number of pixels of the plain-image and L is the number of all possible different pixel values. Moreover, the strength against known/chosen-plaintext attack is also discussed briefly when the iteration number of the two basic parts is more than one.
