Twofish is a 128-bit block cipher submitted as an AES candidate [SKW+98]. Mirza and Murphy [MM99] recently noted two interesting properties in the Twofish key schedule for 128-bit keys: there is a non-uniform distribution of 128-bit whitening keys, and the 64-bit round subkeys are non-uniformly distributed over each subset of keys that fixes the S-boxes. This paper extends these results and exp...
