ABSTRACT
The world of secret codes has always fascinated young and old alike. There is an air of mystery involved in the world of secret agents trying to discover the enemy’s plans before the enemy discovers theirs. In reality most of this work is usually carried out by mathematical boffins in some back room, and not by secret agents sneaking around out there in the real world. This is because the sort of work required to solve these codes is highly logical in its structure.
