Methods for Linear and Differential Cryptanalysis of Elastic Block Ciphers [chapter]

Debra L. Cook, Moti Yung, Angelos D. Keromytis
Lecture Notes in Computer Science  
With this question in mind, we analyze elastic block ciphers and consider the security against two basic types of attacks, linear and differential cryptanalysis.  ...  The structure of elastic block ciphers allows us to use a state transition method to compute differentials for the elastic version from differentials of the round function of the original cipher.  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the NSF or the U.S Government.  ...

Towards Key-recovery-attack Friendly Distinguishers: Application to GIFT-128

Rui Zong, Xiaoyang Dong, Huaifeng Chen, Yiyuan Luo, Si Wang, Zheng Li
2021 IACR Transactions on Symmetric Cryptology  
When analyzing a block cipher, the first step is to search for some valid distinguishers, for example, the differential trails in the differential cryptanalysis and the linear trails in the linear cryptanalysis  ...  A distinguisher is advantageous if it can be utilized to attack more rounds and the amount of the involved key bits during the key-recovery process is small, as this leads to a long attack with a low complexity  ...  Acknowledgments The authors would like to thank the anonymous referees for their helpful comments.  ...

Elastic block ciphers: method, security and instantiations

Debra L. Cook, Moti Yung, Angelos D. Keromytis
2009 International Journal of Information Security  
We demonstrate the general applicability of the elastic block cipher method by constructing examples from existing block ciphers: AES, Camellia, MISTY1 and RC6.  ...  Our method is designed to enable us to form a reduction between the elastic and the original versions of the cipher.  ...  These attacks typically attempt to recover the keys or the round keys of the block cipher; differential [7, 18] , linear [20] and exhaustive search methods are instances of such attacks (but other attacks  ...
