Course Objectives
|
To understand the cryptanalysis of ciphers
Outcome:
First module of the course is meant for introducing the classical methods of cryptanalysis. Module 2, 3 and 4 all have contents of the modern cryptanalytic techniques of Cryptographic primitives. The outcome will be the knowledge of analysis techniques for encryption algorithms which will help in evaluating the cryptosystems as well as designing new systems.
