Summary:
The problem of how to send a message confidentially has exercised minds for thousands of years. The battle between the cryptographer (who writes the message) and the cryptanalyst (who intercepts and tries to decipher it) has ebbed and flowed. In this illustrated talk, I shall look at selected ciphers from the simple to the most modern to see how this contest has developed over the years and perhaps determine who is currently winning!
