It was not that long ago that, Sir Tim Burners-Lee invented the WWW. He realised that the internet (a network of computers across the world) could be used to share information. He came up with the idea of ‘Hypertext’ – this is simply text which links to other text as shown by the diagram below:

The following messages are the result of a left shift 3 spaces Caesar Cipher (where each letter of the original message has been shifted to the left 3 spaces). Use the table above to help you decipher the following messages. (The key has capital letters only so ensure that you write all of your answers

The following messages are the result of a right shift 3 spaces Caesar Cipher (where each letter of the original message has been shifted to the right 3 spaces). Use the table above to help you decipher the following messages. (The key has capital letters only so ensure that you write all of your answers

Study the ‘PigPen Cipher Key’, then use it to crack the three codes below. (The key has capital letters only so ensure that you write all of your answers in capital letters!)

Who is this man shown above and what did he do that was so important? (You are expected to write in full sentences and discuss the issues faced during the war with German encrypted messages and how this man helped in the process of decrypting messages through the use of an invention).
