摘要

证明了二值图像隐写算法CPT的等价密钥量为2

.把CPT算法看成一个特殊的分组密码

利用差分分析给出了一个求等价密钥的快速算法

该算法需要mn对明密文

时间复杂度为

Abstract

CPT is a data hiding scheme for binary images.In this paper

we prove that there are 2

mn-r

equivalent keys for CPT.Moreover

by viewing the CPT as a block cipher

we propose a fast key searching algorithm with difference analysis

which can succeed in output a equivalent key given mn pairs of plain and cipher data with negligible time complexity

O(2

)
