Fridrich混沌图像加密方案的密码学分析

On the cryptanalysis of Fridrich's chaotic image encryption scheme

Eric Yong Xie, Chengqing Li, Simin Yu, Jinhu Lü

摘要:

在过去的25年里,人们对利用混沌映射和混沌系统的复动力学特性进行加密进行了广泛的研究。1989年,Fridrich提出的混沌图像加密方案是通过对混沌位置置换和值置换迭代若干轮而设计的,在混沌密码学领域引起了广泛的关注。2010年,Solak \textit{et al.}提出了一种利用密文像素和对应的明文像素之间的影响网络对Fridrich方案进行选择密文攻击的方法。本文在他们创造性工作的基础上,用简明的数学语言研究了Fridrich格式的一些性质。最后,给出了Solak攻击方法在实际性能上的一些小缺陷。为进一步优化对Fridrich方案及其变种的攻击提供了依据。

英文摘要:

Utilizing complex dynamics of chaotic maps and systems in encryption was studied comprehensively in the past two and a half decades. In 1989, Fridrich's chaotic image encryption scheme was designed by iterating chaotic position permutation and value substitution some rounds, which received intensive attention in the field of chaos-based cryptography. In 2010, Solak \textit{et al.} proposed a chosen-ciphertext attack on the Fridrich's scheme utilizing influence network between cipher-pixels and the corresponding plain-pixels. Based on their creative work, this paper scrutinized some properties of Fridrich's scheme with concise mathematical language. Then, some minor defects of the real performance of Solak's attack method were given. The work provides some bases for further optimizing attack on the Fridrich's scheme and its variants.
