IMPORTANT
Just a reminder that, owing to maintenance on the University servers, the Cipher Challenge website will be unavailable from 3rd-6th January 2012. This contains the original final deadline for challenge 8 (4th January), so we have extended the submission deadline to 23.59 on  January 11th. The marks scheme is given below:
