A Meet in the Middle Attack on Reduced Round Kuznyechik
... Abstract. Kuznyechik is an SPN block cipher that has been recently chosen to be standardized by the Russian federation as a new GOST cipher. The algorithm updates a 128-bit state for nine rounds using a 256-bit key. In ...

A Meet-in-the-Middle Attack on Round-Reduced mCrypton Using the Differential Enumeration Technique
... The meet-in-the-middle (MITM) attack was first introduced by Diffie and Hellman in 1977 [8]. In the past decade, the MITM scenario has become one of the most fruitful cryptanalysis method. It has been used ...
