Secure Socket Layer (SSL) was first proposed and used by Netscape to transmit sensitive data over the internet by encapsulating it in a session on top of the TCP layer. SSL aims to authenticate parties, ensure data integrity, and maintain data privacy. Certain websites can only be accessed through SSL-enabled client software. SSL establishes an association between a client and server by authenticating them and then exchanging and encrypting data using suitable algorithms to keep the information secret. SSL has two layers - the record protocol, which handles data encryption, integrity, and encapsulation, and several subprotocols like the alert, change cipher spec, and handshake protocols, which initiate and negotiate secure sessions.
Secure Socket Layer
- 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 : οΌ Authenticate οΌ Data Integrity οΌ 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
- 9. SSL has 2 layers Protocol required for connection and during communication Record protocol
- 10. Record Protocol οΌ Data Encryption οΌ Integrity οΌEncapsulation of data and sending
- 11. How ? By: οΌ Fragmentation οΌ MAC οΌ Compression οΌ Encryption οΌ 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 οΌInitiates session οΌNegotiate key sizes οΌMutual authentication
