Improved Impossible Differential Attack on Reduced-Round LBlock
Lecture Notes in Computer Science, 2016LBlock is a 32-round lightweight block cipher with a 64-bit block size and an 80-bit key. This paper presents a new impossible differential attack on LBlock by improving the previous best result for 1 more round. Based on the nibble conditions, detailed differential properties of LBlock S-Boxes and thorough exploration of subkey relations, we set up ...

Related-Key Impossible Differential Attack on Reduced-Round LBlock
Journal of Computer Science and Technology, 2014LBlock is a 32-round lightweight block cipher with 64-bit block size and 80-bit key. This paper identifies 16-round related-key impossible differentials of LBlock, which are better than the 15-round related-key impossible differentials used in the previous attack.

New Related-Key Impossible Differential Attack on MIBS-80
2016 International Conference on Intelligent Networking and Collaborative Systems (INCoS), 2016MIBS is a lightweight block cipher designed by M. Izadi et al in 2009 for tiny computing devices, such as RFID tags and sensor network nodes. The cipher algorithm iterates a Feistel structure with SP type round function by 32 rounds. It with 64-bit block size and supports 64/80-bit key size.

New Impossible Differential Attacks on AES
2008In 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 previously known attacks due to Bahrak-Aref and Phan. The improvement of these attacks leads to better impossible differential attacks on 7-round AES-128 and ...

New Impossible Differential Attacks on Camellia
2012Camellia 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 FL/FL−1 layers, which turn out to be the first 7-round impossible differentials with 2 FL/FL−1 layers.

Note on Impossible Differential Attacks
2016While 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 solve that, Boura et al.i¾?[1] presented at ASIACRYPT'14 a generic vision of impossible differential attacks with the aim of simplifying and helping the ...

Impossible-Differential Attacks on Large-Block Rijndael
2007This paper reports impossible-differential (ID) attacks on reduced-round versions of the Rijndael cipher with text blocks larger than 128 bits. These attacks follow the framework of the attacks by Biham-Keller and Cheon et al. on the AES, and reach up to seven rounds of large-block Rijndael variants.
