With the coming of the computer age both the field of cryptography and the mathematics supporting it have been reawakened. This talk will address the history of cryptography beginning with the Enigma used by the Germans in WWII and broken by world famous mathematician and computer scientist Alan Turing. It will continue down to today’s advanced crypto systems such as RSA, PGP and Elliptic Curve cryptography. The lecture will point out the key role that cryptography plays in the future of e-commerce and the new products and ways of doing business that result when secure communications through cryptography are available.
