Impossible Differential Cryptanalysis of Surge
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In 2018, Li Lang et al. proposed a new lightweight block cipher which is called Surge. Its block size is 64-bit, and the length of key size is 64/80/128-bit, respectively. They also proved that the cipher has good performance on security and effectively resists on differential attack, linear attack and algebraic attack.

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 ...

Impossible Differential Cryptanalysis of Zodiac [PDF]
, 2002 We discuss the impossible differential cryptanalysis of the blockcipher Zodiac. The main design principles of Zodiac are simplicity and efficiency. However the diffusion layer in its round function is too simple to offer enough security. An impossible differential cryptanalysis is a proper method to attack the weakness of Zodiac.

Impossible Differential Cryptanalysis of CLEFIA [PDF]
, 2008 This paper reports impossible differential cryptanalysis on the 128-bit block cipher CLEFIA that was proposed in 2007, including new 9-round impossible differentials for CLEFIA, and the result of an impossible differential attack using them. For the case of a 128-bit key, it is possible to apply the impossible differential attack to CLEFIA reduced to ...
