Information theory, error control coding and cryptography are the three load-bearing pillars of modern digital communication systems. All the three topics are vast, and there are many good books that deal with these topics individually. In this book, an attempt has been made to incorporate all the important concepts of information theory, error control coding and cryptography in-between the two covers, without making the covers too far apart. This is intended as a simple and lively book on the subject.
