## Mathematical Methods in Cryptography

##### Abstract:

Cryptography has a long history, dating back to the first century BC. The twentieth century saw huge advances in cryptography as systems for rapid long-distance communications developed, to the point where now cryptographic practices are used on a daily basis for commonplace activities such as checking email. In this talk I will give a brief survey of mathematics that go into the modern practice of cryptography, in both designing and attacking cryptographic systems.
