Description Well-known examples of codes include Morse, ASCII, ISBN book numbers, as well as the bar code used on grocery items. A code provides a way of converting a message into a form suitable for transmission or storage and usually entails some binary procedure suitable for an electronic device. In this unit, students study how this can be achieved efficiently and how an appropriate error-correcting capacity can be built in. A cipher is a secret code, examples being 'one-time pads' which are essentially unbreakable provided they are used only once. The unit describes the structure as well as some of the weaknesses of several cryptosystems including DES and the RSA public key cryptosystem, which is widely used these days. The concepts and content of this unit underpin some of the security aspects of electronic commerce (electronic signatures, authentication and security protocols).
