Empirical Verification of Twofish Key Uniqueness Properties

D. Whiting, D. Wagner

Twofish Technical Report #2, September 22, 1998.

ABSTRACT: Twofish is a 128-bit block cipher submitted as an AES candidate. Each distinct Twofish key generates a unique sequence of subkeys Ki, and each round function F is unique for a distinct value of the S bits used to generate the S-boxes. Thus, no two distinct keys result in an identical sequence of round functions.
