In this post we have posted some notes on CS8792 CRYPTOGRAPHY AND NETWORK SECURITY of PROFESSIONAL CORE for ANNA UNIVERSITY AFFILIATED COLLEGES STUDENTS. 

Here We have listed the the notes whichever we could collect for CS8792 CRYPTOGRAPHY AND NETWORK SECURITY subject, We think that it will be helpful for your exam preparation.

👉 To understand Cryptography Theories, Algorithms and Systems.

👉 To understand necessary Approaches and Techniques to build protection

mechanisms in order to secure computer networks.

Security trends – Legal, Ethical and Professional Aspects of Security, Need for Security at Multiple levels, Security Policies – Model of network security – Security attacks, services and mechanisms – OSI security architecture – Classical encryption techniques: substitution techniques, transposition techniques, steganography- Foundations of modern cryptography: perfect security – information theory – product cryptosystem – cryptanalysis.

Algebraic structures – Modular arithmetic-Euclid‟s algorithm- Congruence and matrices – Groups, Rings, Fields- Finite  fields- SYMMETRIC KEY CIPHERS: SDES – Block cipher Principles of DES – Strength of  DES – Differential and linear cryptanalysis – Block cipher design principles – Block cipher mode of operation – Evaluation criteria for AES – Advanced Encryption Standard – RC4 – Key distribution. 

Primes – Primality Testing – Factorization – Euler‘s totient function, Fermat‘s and Euler‘s Theorem – Chinese Remainder Theorem – Exponentiation and logarithm – ASYMMETRIC KEY CIPHERS: RSA cryptosystem – Key distribution – Key management – Diffie Hellman key exchange – ElGamal cryptosystem – Elliptic curve arithmetic-Elliptic curve cryptography. 

Authentication requirement – Authentication function – MAC – Hash function – Security of hash function and MAC – SHA –Digital signature and authentication protocols – DSS- Entity Authentication: Biometrics, Passwords, Challenge Response protocols- Authentication applications – Kerberos, X.509 

Electronic Mail security – PGP, S/MIME – IP security – Web Security – SYSTEM SECURITY: Intruders – Malicious software – viruses – Firewalls.  

At the end of the course, the student should be able to:

👉 Understand the fundamentals of networks security, security architecture, threats and vulnerabilities 

👉 Apply the different cryptographic operations of symmetric cryptographic algorithms

👉 Apply the different cryptographic operations of public key cryptography

👉 Apply the various Authentication schemes to simulate different applications.

👉 Understand various Security practices and System security standards .
