Abstract
The alleged RC4 keystream generator is examined, and a method of explicitly computing digraph probabilities is given. Using this method, we demonstrate a method for distinguishing 8-bit RC4 from randomness. Our method requires less keystream output than currently published attacks, requiring only 230:6 bytes of output. In addition, we observe that an attacker can, on occasion, determine portions of the in- ternal state with nontrivial probability. However, we are currently unable to extend this observation to a full attack.
