Quantum impossible differential attacks: applications to AES and SKINNY
Designs, Codes and Cryptography, 2023 This article is devoted to quantum cryptoanalysis of block ciphers. The resistance of symmetric primitives against attack using quantum algorithms is considered. The proposed methods may provide no more than quadratic speedup without immediate threat to considered ciphers and discussed for a better understanding of post-quantum security margins.

Multiple Impossible Differential Attacks for ForkAES
Security and Communication Networks, 2022 To yield a highly efficient authentication encryption design for very short messages, the tweakable forkcipher is proposed, which is a tweakable block cipher that uses forking construction to produce two output blocks. The designers also presented ForkAES, a forkcipher that is based on the round function of AES and the tweakable variant of KIASU ...

An Improved Impossible Differential Attack on MISTY1 [PDF]
, 2008 MISTY1 is a Feistel block cipher that received a great deal of cryptographic attention. Its recursive structure, as well as the added FL layers, have been successful in thwarting various cryptanalytic techniques. The best known attacks on reduced variants of the cipher are on either a 4-round variant with the FL functions, or a 6-round variant without ...

New Impossible Differential Attack on SAFER + and SAFER + + [PDF]
, 2013 SAFER+ was a candidate block cipher for AES with 128-bit block size and a variable key sizes of 128, 192 or 256 bits. Bluetooth uses customized versions of SAFER+ for security. The numbers of rounds for SAFER+ with key sizes of 128, 192 and 256 are 8, 12 and 16, respectively. SAFER++, a variant of SAFER+, was among the cryptographic primitives selected
