Description
The aim of this course is to introduce the student to the area of computer Network Security. This course develops a basic understanding of the algorithms used to protect the flow of information in Computer networks and to understand some of the design choices behind these algorithms.
The content of this course are as follows:
Section 1: Introduction
What is Computer Network Security?
Friends And Enemies: Alice, Bob and Eve
Section 2: Principles Of Cryptography
The Terminologies Of Cryptography
Two Domains Of Cryptography-Symmetric Key Cryptography & Public Key Cryptography
Traditional Ciphers and its Types
Example Of Shift Cipher-Caesar Cipher
Example of Transposition Cipher
Section 3: The Modern Ciphers
DES and Triple DES
Advanced Encryption Standard (AES)
Modes of Operation for block cipher: ECB, CBC,CFB, OFB
Section 4: Asymmetric key cryptography
Rivest, Shamir, Adleman (RSA) Algorithm
Diffie-Hellman Key Exchange Algorithm
Man In The Middle Attack
Section 5: Message Authentication-Integrity Protection Using Digital Signatures
Hash Functions-MD5 and SHA-1
Role Of Certification Authorities in Public Key Encryption
Section 6: End Point Authentication Scenarios to avoid man in the middle attack
Section 7: Securing The E-mail
Pretty Good Privacy (PGP) to secure e-mail
Section 8: Transport Layer Security Using TLS/SSL
TLS Security Services (TLS) Services
The bigger picture-Toy TLS/SSL Example
