(1229) Encoding Fractionated Morse

Introduction to Fractionated Morse

• Focus on encoding of fractionated Morse to facilitate decoding.

Encoding Process

Example Sentence

• Utilize the sentence: "My name is Tom."

Step 1: Morse Code Table

• Convert plain text into Morse code:

  • M: -- (two dashes)

  • Y: -..- (dash dot dash dash)

  • Use "X" to indicate end of each letter.

  • Use "X" (cross) twice to indicate end of a word.

Detailed Conversion

• My:

  • M: --

  • Y: -..-

  • End of word: XX

• name:

  • N: -.

  • A: .-

  • M: --

  • E: .

• is:

  • I: ..

  • S: ...

  • End of word: X

• Tom:

  • T: -

  • O: ---

  • M: --

Complete Morse Encoding

• Final Morse encoding for "My name is Tom" includes break indications and end notations.

Fractionated Morse Encoding

Step 2: Break Morse Code into Sets

• Split Morse code into sets of three characters:

  • Example: First set, second set, etc.

Step 3: Creating Replacement Table

• Utilize the keyword "Buster" for mapping!

  • Start with the letters from the keyword, filling the alphabet alphabetical order:

    • B, U, S, T, E (already taken), R, F, G, H, I, J, K, L, M, N, O, P, Q.

Mapping Morse Codes to Letters

• Assign values based on the three-character sets:

  • D-X = J

  • -..- = F

  • -... = G

  • ..-. = U

  • Continue with assignments until completed.

Conclusion

• The fractionated Morse cipher for "My name is Tom" using key "Buster" results in a unique string of letters.

• Understanding this encoding process is crucial for decoding fractionated Morse ciphers.
