The lecture titled "Public Key Cryptography: Computation, Cash and John Nash" will explain how security can be enhanced by the use of hard computational problems from Mathematics. This was the basis for the creation of publi c key cryptography in the 1970s. Public key cryptography has many applications in information security, such as secure internet shopping, digital signatures and secure automatic software updates. We will see how digital signatures have now become a crucial component of the electronic currency bitcoin. Cryptography is, of course, of great interest to national security. Recently (only declassified in 2012) it has been revealed that John Nash (subject of the film A Beautiful Mind) sent a letter to the United States National Security Agency in 1955. His letter outlined new concepts that anticipated by decades fundamental notions in computational complexity and modern cryptography.
