Network Security Handout

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 also dwells 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.

Note :

It shall be the responsibility of the individual student to be regular in maintaining the self study schedule as given in the course handout, attend the online/on demand lectures as per details that would be put up in the BITS DLP website http://www.bits-pilani.ac.in/dlp-home/ or http://202.54.26.115/bits/Portal/dlpd/ and take the prescribed components of the evaluation such as mid semester test, comprehensive examination as per scheduled dates in the course handout. If the student is unable to appear for the regular test/examination due to genuine exigencies, the student must refer to the procedure for applying for make-up test/examination, which will be available through the Important Information link on the BITS DLP website.
