A superencryption substitution + transposition

In his booklet dated 28 June 1606 and aimed at his pupils in a course of cryptography, Pietro Partenio presents several ciphers consisting mostly of a nomenclator followed by some form of super-encryption. In this first cipher, this is done using a transposition, quite unusual; it may be the first of this kind, which in fact only began to be used in the 19th century *. Nowadays alternating substitution and transposition is the rule in ciphers like Feistel, DES and AES, but of course these ciphers are designed to be executed by computers not by humans.

And for human beings, particularly for XVII century secretaries, such a procedure was likely too demanding and error prone. Among the papers of the Venetian archives I could not find a single message encrypted with this cipher, that is interesting from a theoretical point of view only.

Encrypting procedure

The base nomenclator is the typical nomenclator having alphabet, syllabary and dictionary; it uses ciphers made of two letters, like as, ap; using a 20 letters alphabet, one has 400 ciphers available, enough heft for a nomenclator (see below). There are no homophones or nulls, in line with what was stated by Partenio in one of his memoirs, that homophones and nulls are useless because the secretaries, not being obliged to do so, do not use them or use them badly.

Superencryption is based on a verse to be held in memory without writing it; one writes the verse without spaces and grouped in 10 letters blocks; one writes the numbers from 0 to 9, under the letters following this rule; in each 10-block one marks the a, if present, starting with 0*, then marks orderly the b, c and so on, up to have 10 numbers under 10 letters; one continues under the second block of 10, and so on up to the end of the message.

These numbers are the actual transposition key: now one has to write the letters of the ciphertext orderly under the number, as shown on the right.


Interactive example
Cipher-text to be deciphered
Spaces are automatically removed.
1) Reverse transposition:
One writes every letter of the cipher-text following the numbers of the key; so the first letter is the one above the first zero, here and is written at the first place; thereafter one takes the letter under the secondo zero, here and writes after the first and so on.
5
2) Decipher using the nomenclator:

On the right you see Partenio's example used in his book; the message is: "Il Turco arma molte galee dubito per Candia", and the verse is Lex tua meditatio mea uoluntas tua cordi meo est.

Both can be modified using the two input windows in the top right frame. Important: if you try to encrypt a free text, please consider this cipher was designed for the XVII century Italian language and alphabet. Using another language, like English, can result in a few problems: 1) letters j, k, v, w, x, y are missing here, you can only use similar letters. e.g.: j → i, k → q or c, v → u, w → uu, x → cs, y → i. 2) the dictionary will be scarcely used, and encryption will revert to use syllables or single letters.

The step-by-step procedure is shown, in the frame on the right.

In the frame below one can decipher any cipher-text using this cipher; clicking the green button one can import the above cryptogram.

Here is the base nomenclator, the first step of the cipher; as stated above, it is s two letters system, ordered in a way one can rebuild alphabet and syllabary by heart using this mnemonic key: spirtquandchlofzgemb; indeed every letter is encrypted by a couple of letters having a as the first one, followed by the letter of the key.

Similar is the syllabary, having 7 rows of 4 quintuples of syllables, 140 as a whole; the first letter is the one of the row from the letters spirtqu, the second is the one of the column. As a whole alphabet and syllables use 160 two-letters ciphers. So if one remembers the mnemonic key it is possible to recover the syllabary also. Easy of use that is a weakness also, easing the cryptanalist's task also.

X Indeed Partenio begins from 1 and has 0 as the last number, mathematically bizarre. Here to simplify the procedure I preferred to begin with 0.
X It is often mentioned as the first of this kind, at least among the published ones, the 1869 dictionary of Benoit Brunswick, listed among the references, bottom page.
