I participated in UK Cyber Security Challenge.
Our university team won the competition.
It was an interesting experience and through teamwork we solved all the challenging puzzles other universities had submitted.
Try to crack Christmas Cipher 2012 to practice for upcoming UK Cyber Security challenges.
