Discussion Overview

The thread discusses the challenge of solving a cryptogram presented as a homework problem. Participants explore methods for decoding the cryptogram, focusing on techniques such as frequency analysis and monoalphabetic substitution ciphers.

Discussion Character

  • Homework-related, Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant, Crazysah, has attempted frequency counting and mono-alphabetic substitution but has not succeeded in decoding the cryptogram.
  • Another participant suggests that the cryptogram is likely a monoalphabetic substitution cipher and proposes that identifying the first few letters through frequency analysis may help in determining a keyword for the cipher.
  • A later reply indicates that the cryptogram may be a monoalphabetic substitution cipher, noting that some letters might repeat, which could be a key to solving it.
  • One participant questions whether the cryptogram could be a polyalphabetic substitution cipher based on the frequency distribution observed.
  • Another participant encourages Crazysah to share the results of their frequency analysis to facilitate further assistance.

Areas of Agreement / Disagreement

Participants generally agree that the cryptogram is likely a monoalphabetic substitution cipher, but there is no consensus on the specific method or keyword to use for decoding it. The discussion remains unresolved regarding the exact nature of the cipher.

Contextual Notes

Participants mention that spaces and punctuation have been removed from the cryptogram, which may complicate the decoding process. There is also uncertainty about the effectiveness of the attempted methods and the specific characteristics of the cipher.

Homework Equations



Use whatever tools you wish (though we recommend the frequency-analysis and monoalphabetic substitution-cipher tools, some serious elbow grease and some ingenuity) to uncover the plaintext.
That is the cryptogram without any spaces for punctuation.

The Attempt at a Solution



Now I've tried to use frequency counting and a mono-alphabetic substitution cipher with no luck.

Anybody have any idea on this one?

Thanks,
Crazysah

is this for a course?

The suggestion of using frequency analysis and monalphabetic subs tools means its probably a monoaphabetic substitution cipher. If you can identify the first few letters via the freq analysis then you might find they used a keyword to construct the cipher. As an example: dumbwaiter where d=a / u=b / m=c / b=d... followed by the remaining letters in order that aren't in dumbwaiter.
 
Yes. He says it is something we haven't done in class before and we have done monoalphabetic substitution ciphers before. Also, I already tried using a keyword but I'm just not getting the right keyword. I tried identifying the first few letters to form a word but no luck.
 
Do you have ideas on what the cipher may be? From frequency analysis you can get a feel for what you are dealing with. (e.g. a flatter frequency distribution may be a polyalphabetic substitution cipher.)
 
No. I do not know what the cipher may be but I'm thinking it may be closest to a monoalphabetic substitution cipher.
Also, some letters may repeat itself. I think that might be the trick.
Just to say it again: Spaces and punctuation have been removed

If you have done the frequency count, why not post the results of it? It seems that would increase the chances that somebody could help you out.
