Public Key Cryptography
Friday 14th May, 2010 16:00-17:00 Mathematics Building, room 515
A public key cryptosystem is a way of sending messages securely where knowledge of the enciphering process does not make a message significantly easier to decode. The security of the system is based on the difficulty of some mathematical problem. In this talk I will describe some of the problems which can be used and show in some examples how they can be implemented.
