General Impossible Differential Attack on 7-Round AES
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2010 Impossible differential attack (IDA) uses impossible differential characteristics extracted from enough plaintext pairs to retrieve subkeys of the first and the last several rounds of AES. In this paper, a general IDA on 7-round AES is proposed. Such attack takes the number of all-zero columns of the 7th and the 6th round as parameters (α, β).

A new impossible differential attack on SAFER ciphers
Computers and Electrical Engineering, 2010This paper presents an improved impossible differential cryptanalysis of SAFER ciphers, which uses the miss-in-the-middle technique developed by Biham et al. We analyze 3.75-round SAFER SK-64, using 2^4^5 chosen plaintexts, 2^3^8 bytes memory and 2^4^2 half round computations. Furthermore, the new impossible differential attack on 3.75-round SAFER+/128

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 ...

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 ...

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.

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.

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.
