"I thought at first that this was a simple transposition cipher.

Many transposition ciphers are done according to a geometric design.

K3 is a transposition cipher, and K4 is still unsolved.

Scytale, an encryption tool used to perform a transposition cipher.

The later variants of the Cardano grille present problems which are common to all transposition ciphers.

In a transposition cipher, the letters themselves are kept unchanged, but their order within the message is scrambled according to some well-defined scheme.

Alternatively, use a keyed columnar transposition cipher with 'magnitude' as your key word."

They include simple substitution ciphers and transposition ciphers.

Another form of transposition cipher uses grilles, or physical masks with cut-outs, rather than a mathematical algorithm.

Substitution ciphers can be compared with transposition ciphers.

One of his first challenges (resisted by the establishment) was to phase out double transposition ciphers using keys based on preselected poems.

Trying to find this permutation is essentially the same problem encountered when analysing a columnar transposition cipher: multiple anagramming.

Classical ciphers are often divided into transposition ciphers and substitution ciphers.

Other examples include the Vertical Parallel and the Double Transposition Cipher.

Many anti-Stratfordians search for hidden messages in the form of acrostics and transposition ciphers, although this approach is not so popular with Marlovians.

Lidenbrock attempts a decipherment, deducing the message to be a kind of transposition cipher; but his results are as meaningless as the original.

During World War I, the German military used a double columnar transposition cipher, changing the keys infrequently.

Transposition cipher: the ciphertext is a permutation of the plaintext (Rail fence cipher)

Multiple anagramming is a technique used to solve some kinds of cryptograms, such as a permutation cipher, a transposition cipher, and the Jefferson disk.

"Rail Fence Cipher" (also called a zigzag cipher) generally refers to a form of transposition cipher.

The players face simple substitution and transposition ciphers, graphic and multimedia ciphers, object with the clue hidden inside that must be destroyed, and more.

In classical cryptography, a permutation cipher is a transposition cipher in which the key is a permutation.

In a transposition cipher, the units of the plaintext are rearranged in a different and usually quite complex order, but the units themselves are left unchanged.

In fact, the code was a fractionating transposition cipher based on a substitution table of 100 groups of two figures each followed by a columnar transposition.

Gaines, in her standard work on hand ciphers and their cryptanalysis, gave a lengthy account of transposition ciphers, and devoted a chapter to the turning grille.
