Winchester College

Maths Society Talk

Dr Julian Havil delivered a masterful lecture on elliptic curve cryptography. The Science Lecture Theatre was full to capacity with an even mix of Wykehamists and visitors from half a dozen local schools and colleges. Assuming little more than basic algebra, Dr Havil introduced the audience to both elliptic curves and public key cryptography before showing how the two combined to form what is fast becoming the industry standard for secure online communication. He started in the 19th century and ended with cutting edge examples from America's National Security Agency.
