February 1404 in Genua; † end of April 1472 in Rome) is assumed to be the inventor of the ciphering wheel. Most of the relics of that age have been protected using this very cipher. There are several methods of encipherment using the Cipher disk, that were described by Leon Battista Alberti himself in his treatise "De Cifris" in 1467. Created in the 15th century (1466/67), it was the peak of cryptography at that time. In the opening pages of his treatise De componendis cifris he explained how his conversation with the papal secretary Leonardo Dati about a recently developed movable type printing press led to the development of his cipher wheel. The cipher has to include special signals that tell the recipient to change which alphabet they are using. Alberti encoded keys to this system on sets of cipher discs. The Alberti cipher is a polyalphabetic cipher system that uses two mobile concentric disks which can rotate. The next day, Ms. Sneed tried something a little different. AlbertiCipherDisk. ...
