On the Design Rationale of SIMON Block Cipher: Integral Attacks and Impossible Differential Attacks against SIMON Variants
SIMON Lightweight block cipher Integral attack
2016/6/20
SIMON is a lightweight block cipher designed by NSA in 2013. NSA presented the specification and the implementation efficiency, but they did not provide detailed security analysis nor the design ratio...
Automatic Search of Meet-in-the-Middle and Impossible Differential Attacks
automatic search meet-in-the-middle impossible truncated differential
2016/6/7
Tracking bits through block ciphers and optimizing attacks at hand is one of the tedious task symmetric cryptanalysts have to deal with. It would be nice if a program will automatically handle them at...
Note on Impossible Differential Attacks
truncated impossible differential cryptanalysis block cipher
2016/4/6
While impossible differential cryptanalysis is a well-known and popular cryptanalytic method, errors in the analysis are often discovered and many papers in the literature present flaws. Wishing to so...
Improved Impossible Differential Attacks against Round-Reduced LBlock
block ciphers impossible differential attacks LBlock
2016/1/23
Impossible differential attacks are among the most powerful forms of cryptanalysis against block ciphers. We present in this paper an in-depth complexity analysis of these attacks. We show an unifie...
Scrutinizing and Improving Impossible Differential Attacks: Applications to CLEFIA, Camellia, LBlock and Simon (Full Version)
block ciphers impossible differential attacks CLEFIA
2016/1/7
Impossible differential cryptanalysis has shown to be a very powerful form of cryptanalysis against
block ciphers. These attacks, even if extensively used, remain not fully understood because of thei...
New Impossible Differential Attacks on Camellia
secret-key cryptography / Camellia Impossible Differential Cryptanalysis
2012/8/28
Camellia is one of the most worldwide used block ciphers, which has been selected as a standard by ISO/IEC. In this paper, we propose several new 7-round impossible differentials of Camellia with 2 $F...

Camellia Block Cipher Cryptanalysis Impossible Differential Path Impossible Differential Attack
2012/3/30
Camellia is a block cipher selected as a standard by ISO/IEC, which has been analyzed by a number of cryptanalysts. In this paper, we propose several 6-round impossible differential paths of Camellia ...
New Impossible Differential Attacks of Reduced-Round Camellia-192 and Camellia-256
Camellia block cipher Cryptanalysis Impossible differential path Impossible differential attack
2011/1/12
Camellia is a block cipher selected as a standard by ISO/IEC, which has been analyzed by a number of cryptanalysts. In this paper, we propose several 6-round impossible differential paths of Camellia ...
In this paper we apply impossible differential attacks to reduced
round AES. Using various techniques, including the early abort approach and
key schedule considerations, we significantly improve pr...
