The table contains 26 alphabets written in different rows each alphabet is cyclically shifted to the left according to the previous alphabet, equivalent to the 26 possible Caesar Ciphers. Vigener square or Vigenere table is used to encrypt the text. It uses multiple substitution alphabets for encryption.

In Polyalphabetic Substitution, Cipher is a method of encrypting alphabetic texts. Polyalphabetic Cipher is also known as Vigenere Cipher, which Leon Battista Alberti invents. In this type of ciphers, plain text replacement is done through the block by block rather than character by character. In this case, EDUCBA will replace with XYQLAB, but EDU can be replaced with another set of the block, let’s assume EDU will replace with LOD. In polygram substation cipher, rather than replacing each alphabet with another, the alphabets’ Block is replaced with another block of alphabets. or replace A with E, x or L, B with T, A, Z, etc. For example, replace A with x, E with B, S with A, etc. The substitution alphabet is replaced with te fixed. Homophonic Substitution CipherĪ homophonic substitution cipher is similar to a monoalphabetic cipher the only difference is in monoalphabetic, we replace the alphabet with any other random alphabet except the original alphabet wherein homophonic substitution cipher, the alphabet is replaced by fixed alphabet or set of alphabet.

Mono alphabetic cipher causes difficulty to crack the message as there are random substitutions and a large number of permutation and combination are available.

C can be replaced by A, B, and D to z, etc. That is, A can be replaced by any other alphabet from B to Z.

In monoalphabetic, each alphabet in plain text can be replaced by any other alphabet except the original alphabet.
