Nadael Guindy's Cryptographic Gadget Brings Leon Alberti's Cipher Discs to the Arduino UNO
Maker Nadael Guindy has brought a classic of cryptography up to date — by building an Alberti cipher disc powered by an Arduino UNO board.
"In 1467, the quintessential 'Renaissance Man' Leon Battista Alberti changed the world of secrets forever," Guindy explains by way of background to the project. "Alberti invented what is now considered the world's first polyalphabetic cipher: a mechanical device featuring two concentric disks that allowed for encryption far more sophisticated than the simple substitution ciphers that had come before it. By translating Alberti's physical brass rings into an Arduino-powered digital system, this project explores how a tool designed over half a millennium ago can still be evolved using modern electronics."

A substitution cipher is a way to take a plain-text message and protect it against casual...
