Letters worden herschikt door afwisselende posities te nemen.
The skip cipher is a transposition cipher that rearranges letters by extracting them at regular intervals. In the basic form, odd-positioned letters (1st, 3rd, 5th...) are written first, followed by even-positioned letters (2nd, 4th, 6th...). This scrambles the word without changing any individual letters.
Take positions 1,3,5... then 2,4,6... Example: WATER (W1,A2,T3,E4,R5) -> WTR + AE = WTRAE
- WATER -> WTRAE
- HELLO -> HLOEL
- STARS -> SASRT
Zo herkent u het
- Same letters, different order
- Pattern: odd positions first, then even
- No letter substitution
Veelgemaakte fouten
- Looking for substitution patterns
- Miscounting odd/even positions
- Forgetting which set comes first
Stapsgewijze uitwerking
Codeer 'WATER' met het springcijfer
- Nummer de posities: W(1) A(2) T(3) E(4) R(5)
- Haal oneven posities eruit (1, 3, 5): W, T, R
- Haal even posities eruit (2, 4): A, E
- Combineer: oneven eerst, dan even
Antwoord: WTRAE
