Course Description

This course gives a broad introduction to classical and modern cryptography theory. The students will learn about network security principles and practices. Wireless security for the two most popular wireless communication standards CDMA and GSM will be discussed from both the physical layer and network layer perspectives. Upon completion of this course, students should be able to build security related protocols and applications, solve network security problems using cryptographic techniques, analyze the security of existing network systems and provide suitable security countermeasures to the variety of security threats across the spectrum of computing.
