No clear trend emerged other than what we already knew, there is an effect from the masking or the ciphering where the letter frequencies in K4 are evened out.  This means that instead of seeing large numbers of common letters and low frequencies of less common letters, you see a more even distribution.

I figgered if the extremely common and the extremely uncommon were altered then perhaps there was a little bit of symmetric tomfoolery on the part of Ed Scheidt wherein you switch the outliers and leave the middle frequency letters unchanged.

While no, nothing tangible came out of this latest effort, it did inspire me to consider more of how one would go about masking a little under 100 letters.  I’m contemplating three methods right now, if it was me attempting the same type of maneuver.

  1. A transformation from the English plaintext into a different type of symbolic system (Binary, Morse Code, etc.)
  2. A method in which null letters are inserted into the ciphertext to further foil our efforts.
  3. Two separate ciphering mechanisms were employed on two segments of the plaintext and these separate ciphertexts were layered together.

If there is a way to do it then there is a way to reverse it.
