(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.
