  1. Transposition CipherSumber: Rinaldi Munir, ITBhttp://williamstallings.com/Extras/Security-Notes permutasi cipher  menyembunyikan isi pesan dengan mengatur kembali urutan huruf • Reverse Cipher  karakter dituliskan terbalik AKITAMROFNI KINKET

  2. Rail Fence Cipher menuliskan pesan dalam beberapa baris alternatif secara bergantian Cth: TEKNIK INFORMATIKA T K I I F R A I A E N K N O M T K Cipher : TKI IFRA IA ENK NO MTK

  3. Geometric Figure T E K N N I K I F O R M K I T A A TNFKA IOIE KKRT AMIN

  4. Row Transposition Cipher Plaintext dibagi menjadi beberapa blok yang sama besar dengan jumlah karakter sama. Tambah dengan karakter tertentu, jika perlu. Pindahkan beberapa kolom. Cipher  menurut baris (Row) Cth : 4 kolom (1,2,3,4) TEKN 1 3 2 4 TKEN IKIN  IIKN FORM FROM ATIK AITK AXXX AXXX Cipher : TKEN IIKN FROM AITK AXXX

  5. Block(Columnar) Transposition Cipher  seperti Row Transposition Cipher, Cipher  menurut kolom (Column) Cth : 4 kolom (1,2,3,4) TEKN 1 3 2 4 TKEN IKIN  IIKN FORM FROM ATIK AITK AXXX AXXX Cipher : TIFAA KIRIX EKOTX NNMKX

  6. Nihilist Transposition Cipher  Row Transposition  Baris ditransposisi juga Cipher  menurut baris Cth : 4 kolom (1,2,3,4) 1 TEKN 1 3 2 4 1 TKEN 2 IKIN  2 IIKN 3 FORM 4 FROM 4 ATIK 5 AITK 5 AXXX 3 AXXX Cipher : TKEN IIKN AXXX FROM AITK

  7. Diagonal Transposition Cipher  Row Transposition Cipher secara diagonal. TEKN 1 3 2 4 TKEN IKIN  IIKN FORM FROM ATIK AITK AXXX AXXX Cipher : TKIF IENK RAAI ONMT XXKX

  8. Penggabungan Substutisi dan Transposisi(ADFGVX Product Transposition Cipher ) • Hanya menggunakan ADFGVX saja • Tabel substitusinya tetap. plaintext  sepasang huruf (brs,kolom) • Menggunakan Blok Transposition

  9. Tabel substitusi : \\ A D F G V X Plaintext : A K Z W R 1 F T E K N I K D 9 B 6 C L 5 Intermediate : F Q 7 J P G X XV GA AA GX XF AA G E V Y 3 A N V 8 O D H 0 2 X U 4 I S T M

  10. Kemudian dilakukan transposisi kolom dengan suatu kunci. Cth : AKU (213) XV GA AA GX XF AA XVG  VXG AAA AAA GXX XGX FAA AFA Cipher : VAXA XAGF GAXA
