WebA polyalphabetic cipher is a type of encryption algorithm that uses multiple substitution alphabets to obscure the meaning of a message. The basic idea behind a polyalphabetic cipher is to use multiple substitution alphabets, rather than just one, to obscure the message. This makes it more difficult for attackers to break the cipher, as they ... WebMonoalphabetic Cipher & Polyalphabetic cipher in Cryptography
WebIn a polyalphabetic cipher, multiple cipher alphabets are used. To facilitate encryption, all the alphabets are usually written out in a large table, traditionally called a tableau. The tableau is usually 26×26, so that 26 full ciphertext alphabets are available.
