Math 422 Coding Theory & Cryptography

These lecture notes are designed for a one-semester course on error-correcting codes and cryptography at the University of Alberta. I would like to thank my colleagues, Professors Hans Brungs, Gerald Cliff, and Ted Lewis, for their written notes and examples, on which these notes are partially based (in addition to the references listed in the bibliography) and also Professor Jochen Kuttler, for pointing out several errors in an earlier version of these notes. The figures in this text were drawn with the high-level vector graphics language Asymptote (freely available at http://asymptote.sourceforge.net).
