Alice and Bob have secrets they want to talk about without Eve being able to listen in. Worse yet, the mischievous Mallory delights in changing messages sent between parties. In such a hostile environment how can Alice talk to Bob without their messages being overheard and how can she be sure that it was Bob that sent the message in the first place? This talk will take a brief look at historic codes and ciphers before taking a look at modern day Cryptography. If you want to be able to know the difference between a block cipher and a stream cipher or get a glimpse into the mathematics behind public key Cryptography this talk is for you.

Fantastic history of cryptography that gives an understanding of the topic in today's world

Great talk. Have to say it started going over my head after enigma, but that's my limits of maths rather than the speaker.

Very much enjoyed it.

Decent talk on the basics for those not familiar with encryption, though some more depth in terms of the performance aspects of different algorithms would have been welcomed!
