short and crisp briefing on secure socket layer, much better for revision purposes

1. Secure Socket Layer
Presented by:
Abhishek Gupta
2013MSCLIS 33

2. History
Firstly proposed and used by Netscape also
known for its browser, with a scope of
transmitting sensitive data by encapsulating it
over internet forming a session. It runs on top
of TCP layer

3. Objectives :
 Authenticate
 Data Integrity
 Data Privacy

4. Certain websites get access only through SSL
client software

6. Principle
Idea is to generate an association in between
client and server via getting authentication
then exchanging data and using suitable
algorithm for secrecy of the information

8. Application layer
SSL
TCP
IP

9. SSL has 2 layers
Protocol required for connection and during
communication
Record protocol

10. Record Protocol
 Data Encryption
 Integrity
Encapsulation of data and sending

11. How ?
By:
 Fragmentation
 MAC
 Compression
 Encryption
 Headers

12. Step by step

13. Alert Protocol
Contains two messages :
warning message fatal message

15. Change cipher spec protocol
contains only single message
can be called as acknowledgment
sending protocol

16. Handshake protocol
It performs certain functions
Initiates session
Negotiate key sizes
Mutual authentication
