Cryptography and Network Security
Overview :Computer networks are vital infrastructures needed for our day to day lives. Our increasing reliance on computers and networks of computers calls for robust measures to secure this infrastructure from malicious intents.
Present day networks face continuous threats from hackers. An understanding of the potential perils, and the strengths and limitations of existing solutions to this problem is relevant not only for students specializing in
security, but for every person for whom a computer is an indispensable part of life.
Cryptography, once considered to be solely restricted to the realm of spies and secret service agencies, is an increasingly important building block for realizing computer and network security. An understanding of the principles of cryptography is therefore essential for comprehending approaches to realize secure networks.
The course will introduce private and public key encryption, key distribution (Kerberos, public key infrastructure), cryptographic hash functions, digital signatures, IP Security, Secure Socket Layer, WEP (Wired Equivalent Privacy
for wireless networks), intrusion detection, Firewalls, denial of service, spam, email viruses, phishing, and an overview of many attacks that the Internet has experienced, especially in the last decade.
