The Alan Turing Centenary Cryptography Competition is a cryptography competition aimed at school children in Years 7-11 to celebrate his centenary. It is organised by the School of Mathematics at the University of Manchester. The story follows the adventures of Mike and Ellie, two children who get caught up in a race around Manchester, solving a number of secret codes, as they hunt for the long-lost 'Turing Treasure'. The competition will run from 9th January 2012 to 16th April 2012. There will be 6 chapters to the story and an epilogue. Each chapter contains a code that you will need to solve. The codes get harder as the competition progresses. We aim to release each chapter fortnightly on Monday afternoons at 4pm, according to the schedule below. As soon as your team have cracked the code, you should submit the code word to the competition website using the appropriate link in the left menu. There is a leaderboard on the website, so that you can see how your team is doing compared to others. See below for the scoring system. http://www.maths.manchester.ac.uk/cryptography_competition_2012/
