Construction of Lightweight S-Boxes using Feistel and MISTY structures (Full Version)
S-Box Feistel network MISTY network
2015/12/24
The aim of this work is to find large S-Boxes, typically operating on 8 bits, having
both good cryptographic properties and a low implementation cost. Such S-Boxes are suitable
building-blocks in ma...
In this paper, we first prove beyond-birthyday-bound security for the Misty structure. Specifically, we show that an $r$-round Misty structure is secure against CCA attacks up to $O(2^{\frac{rn}{r+7}}...
From Camellia to p-Camellia: Some Observations on MISTY Structure with SPN Round Function
Block ciphers Camellia p-Camellia Feistel MISTY SPN Structural properties
2011/1/5
At AFRICACRYPT 2010, a parallelized version of the block cipher Camellia, called p-Camellia, was proposed. The high level structure of p-Camellia is MISTY-type, while the round function is SPN-type. I...
基于MISTY结构的可调分组密码的设计与分析
MISTY结构 分组密码 MISTY结构
2012/4/19
对如何不借助于现有的分组密码来直接设计可调分组密码进行了研究。通过在MISTY结构的不同位置添加一个标号，分析了在4轮和5轮MISTY结构上设计可调分组密码的可行性。对4轮结构提出了攻击的方法；对5轮结构提供了安全性理论证明。结果表明，在选择明文攻击下，5轮MISTY结构才能提供安全的可调分组密码。

Misty permutations pseudo-random permutations generic attacks on encryption schemes
2009/8/25
Misty schemes are classic cryptographic schemes used to construct pseudo-random permu-
tations from 2n bits to 2n bits by using d pseudo-random permutations from n bits to n bits. These d
permutatio...
