Difference between Bifid cipher and Transposition cipher

Bifid cipher vs. Transposition cipher

In classical cryptography, the bifid cipher is a cipher which combines the Polybius square with transposition, and uses fractionation to achieve diffusion. In cryptography, a transposition cipher is a method of encryption by which the positions held by units of plaintext (which are commonly characters or groups of characters) are shifted according to a regular system, so that the ciphertext constitutes a permutation of the plaintext.

Similarities between Bifid cipher and Transposition cipher

Bifid cipher and Transposition cipher have 7 things in common (in Unionpedia): Ciphertext, Confusion and diffusion, Cryptography, Plaintext, Polybius square, Substitution cipher, Trifid cipher.

Ciphertext

In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher.

Confusion and diffusion

In cryptography, confusion and diffusion are two properties of the operation of a secure cipher identified by Claude Shannon in his 1945 classified report A Mathematical Theory of Cryptography. These properties, when present, work to thwart the application of statistics and other methods of cryptanalysis.

Plaintext

In cryptography, plaintext or cleartext is unencrypted information, as opposed to information encrypted for storage or transmission.

Polybius square

In cryptography, the Polybius square, also known as the Polybius checkerboard, is a device invented by the Ancient Greeks Cleoxenus and Democleitus, and perfected by the Ancient Greek historian and scholar Polybius, for fractionating plaintext characters so that they can be represented by a smaller set of symbols.

Substitution cipher

In cryptography, a substitution cipher is a method of encrypting by which units of plaintext are replaced with ciphertext, according to a fixed system; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth.

Bifid cipher and Transposition cipher Comparison

Bifid cipher has 12 relations, while Transposition cipher has 32. As they have in common 7, the Jaccard index is 15.91% = 7 / (12 + 32).
