Modern Cryptography

Traditional symmetric or secret key cryptography has historically been the province of government, diplomatic and military users with a requirement for confidentiality. More recently asymmetric or public key cryptography has been developed and taken up to meet the requirements of life in cyberspace. Private individuals are now using it, often unknowingly, to achieve confidentiality and authentication. In this talk we describe how some of these requirements are met.
