About:

Cryptography has been used in one form or another for over 2000 years by parties wishing to send secret messages. Codes were used by Julius Caesar, the courts of Queen Elizabeth I of England, and King Louis XIV of France, and famously by several countries in World War II. With the rise of the Internet, we now all use encryption several times daily. So, isn't the problem of secret communication solved by now? And, if so, what exactly do cryptographers nowadays work on?

This talk gave a tour of modern cryptography, highlighting how the field has changed -- and expanded in scope -- dramatically from the 1970s to today. Along the way, it was discussed that some of the central problems cryptographers are dealing with (and putting into practice) today and see that the central problem of secret communication is (still) not completely solved.
