First Semester 2011-2012

Course Handout

Course No. : SS ZG513

Course Title : Network Security

Instructor : Murali P, K Haribabu

Course Description

The primary goal of the course is to introduce the student to system and application design aspects of

network security including cryptographic, systemic and computational security aspects of the network /

internetwork systems.

Scope and Objectives

The course covers fundamental aspects of security in a modern networked environment with the focus on

system design aspects and cryptography in the specific context of network / internetwork security. It alsodwells into basics of cryptographic techniques, algorithms and protocols required to achieve these properties;

computational issues in implementing cryptographic protocols and algorithms; and system/application design

issues in building secure networked systems.
