Wedding Ring Cipher contest winners
Last month, Bruce Schneier and I announced a public cryptographic challenge: help figure out how to create ciphers and other privacy applications for my code-wheel wedding rings, designed by Bruce and created by Isabel Rucker.
Out of the submissions, there were a couple dozen that were really strong contenders, and Bruce picked two to receive the winner and runner-up prize.
Congrats to Chris Smith for taking first place with The Fidget Protocol and to Philippe Teuwen for taking runner-up with his wedding-ring polyalphabetic substitution cipher.
My wife and I will take great pleasure in using both ciphers to communicate in private!
Thanks, guys -- your prizes are in the mail (and thanks to everyone who contributed suggestions to this!).
