Security Analysis of a Modulo-216 Implementation Variant of the MBRISI Lightweight ARX Block Cipher: Weak Keys, Deterministic Differentials, and Equivalent Keys

An exact security evaluation of a closed modulo-2 16 implementation variant of the lightweight Add–Rotate–XOR (ARX) block cipher named MBRISI, which proves that addition by a fixed round key is affine over GF ( 2 ) 16 if and only if the key belongs to { 0x0000, 0x4000, 0x8000, 0xC000 } , in which case every XOR differe...
