Research on General Permutation Encryption Module Based on Chaos Theory
《International Journal of Technology Management》2014年第7期58-61,共4页Sun Wenjie 
Replacement and substitution encryption are two basic types of encryption historically. The classical encryption algorithm has been compromised now, but they still can play special role for modem cryptnlogy. For examp...

Cryptanalysis of a Substitution-Permutation Network Using Gene Assembly in Ciliates
《International Journal of Communications, Network and System Sciences》2012年第3期154-164,共11页Arash Karimi Hadi Shahriar Shahhoseini 
In this paper we provide a novel approach for breaking a significant class of block ciphers, the so-called SPN ciphers, using the process of gene assembly in ciliates. Our proposed scheme utilizes, for the first time,...

Linear-Differential Cryptanalysis for SPN Cipher Structure and AES
《Wuhan University Journal of Natural Sciences》2007年第1期37-40,共4页WEI Yongzhuang HU Yupu 
Supported by the National Natural Science Foun-dation of China(60503010) and the Foundation of National Laboratory for Modern communications(51436030105DZ0105)
A new attack on block ciphers is introduced, which is termed linear-differential cryptanalysis. It bases the combining of linear cryptanalysis and differential cryptanalysis, and works by using linear-differential pro...

Design of Optimal Diffusion Layers for SPN Block Ciphers
《Journal of Beijing Institute of Technology》2006年第3期292-295,共4页崔灵果 曹元大 
The diffusion layers in substitution-permutation network（SPN） block ciphers are almost invertible linear transformations, which is optimal if the branch number reaches the maximum value. The method of constructing i...
