http://www.crypto-it.net/eng/simple/beaufort-cipher.html WebThe Autokey cipher uses a key word in addition to the plaintext as its key material, this makes it more secure than Vigenere. Beaufort Cipher. Very similar to the Vigenere cipher, but slightly different algorithm. Porta Cipher. The Porta cipher is a polyalphabetic substitution cipher that uses a keyword to choose which alphabet to encipher letters.

The Beaufort cipher, created by Sir Francis Beaufort, is a substitution cipher similar to the Vigenère cipher, with a slightly modified enciphering mechanism and tableau. Its most famous application was in a rotor-based cipher machine, the Hagelin M-209. The Beaufort cipher is based on the Beaufort … See more To encrypt, first choose the plaintext character from the top row of the tableau; call this column P. Secondly, travel down column P to the corresponding key letter K. Finally, move directly left from the key letter to the left … See more The Beaufort cipher should not be confused with the "variant Beaufort" cipher. In variant Beaufort, encryption is performed by … See more Due to the similarities between the Beaufort cipher and the Vigenère cipher it is possible, after applying a transformation, to solve it as a Vigenère cipher. By replacing every letter in the ciphertext and key with its opposite letter (such that 'a' becomes 'z', 'b' … See more WebFind information related to closures and reopening of PSI Test Centers.

As with the Vigenère Cipher, a keyword is used, and it is repeated to create the keystream. The difference is in how the Tabula Recta is used to get to the ciphertext letter.
