CIS 628 Introduction to Cryptography

Barbara Nostrand, Ph.D.

Electrical Engineering and Computer Science

Welcome to Introduction to Cryptography.  Recent advances in computer and telecommunications networking have increased the importance of telecommunications in the computing discipline.  In particular,  advances in distributed and mobile computing place ever greater demands on computer and network security.  While perfect security can only be maintained by physical security,  we need exchange data with distant users.  Consequently,  we devise and use secret codes which we hope can not be broken.  Conversely,  we often want to spy on our neighbors' conversations.  The science of making and breaking codes is called cryptology and is an intensely mathematical discipline.  Mastery of this subject area involves learning both mathematical theory and practical experimental technique.
