Motivated by the paper of researcher 2013, in this paper the authors present several results related to RC4 non-randomness in WPA. They first prove the interesting zig-zag distribution of the first byte and the similar nature for the biases in the initial key-stream bytes to zero. As they note, this zig-zag nature surfaces due to the dependency of first and second key bytes in WPA/TKIP, both derived from the same byte of the IV. Further, they also note that the correlation of certain key-stream bytes to the first three IV bytes provides much higher biases than what had been presented in the paper by researcher.
