The Mathematics of the RSA Cipher

SeaGL 2015

Most people know that RSA depends on some special attributes of very large prime numbers, but little else. The mathematics behind the RSA cipher are subtle but surprisingly accessible. This talk will explain the mechanics and the logic that make the RSA algorithm work. No mathematical skill beyond basic algebra is needed. Come and learn about (one of) the games that prime numbers play.
