Challenge "Monoalphabetic Substitution with Camouflage — Part 6"  

  By: admin on June 30, 2012, 12:59 p.m.

In the previous parts, you broke a monoalphabetic substitution with one camouflage alphabet. Can you find the plaintext even if nine camouflage alphabets have been used?

This is a wonderful challenge, requiring thinking outside the box. It took me dozens of hours (over 8 calendar years :-), and plenty of trial-and-error with new approaches, to find the technique which would work again this tough cipher, and in the process I enjoyed it very much! Huge thanks to Viktor for posting very high-quality challenges.

Thanks also to Peter Mustermann (Gummiboot) who solved this in 2012 already, showing that it is possible to break this cipher.

Congratulations for solving it. :-)

I have to admit that this challenge is somewhere near the edge between level 2 and level 3. Not sure whether it is above or below that edge.

It is always nice to know someone likes your challenges. Recently I do not spend much time on solving anything but if I had more time I would definitely try to solve some of your great challenges too.
