1. Vigenère Tableau Reference –Matt Bishop, Computer Security, Addison Wesley, 2003.

2. Vigenère Tableau The Vigenère tableau is an example of an efficient implementation of the Vigenère cipher. An equivalent algorithm would be –Ci = (Mi + Ki) mod 26 –Where Ci,Mi, and Ki are all integers from 0,..,25, and i is an index for the ciphertext sequence and the key sequence.

3. Vigenère Tableau (p.2) An equivalent table is made up of A-Z as the first row, a shift of 1 letter for the second row, and so on. The columns and rows are labeled A-Z, and represent the plaintext and key character. The ciphertext is found by indexing into the table.
