Agenda
• Introduction
• Objectives of SSL
• Protocols in SSL
• Working of SSL
• Working of Digital Certificate and Public Key in SSL
• Constraints and Advantages
• Conclusion
Introduction
• SSL mainly used for providing security on Web.
• It is originally developed by Netscape.
• Use Key algorithm and Digital SignaturePublic Key AlgorithmPrivate Key Algorithm
• Verisign and Geotrust plays the role of Digital Certificate Provider
• SSL gives security Assurance to both Party(Client and Server)
Objectives
• Authentication of Client and Server
• Ensure Data Integrity
• Securing Data Privacy

Working Of SSL
ClientServer
Client Sends Message to yelp.com Server
Yelp.com Server also sends message back to the client
Public and Private key identification
Hash Negotiation
Client make reqest for DATA
Yelp.com sends data to client
Working Of Digital Signature in Context to SSL
•Working as a Permission Pass
•Issues certificate to identify the person and also public key
Contains Various Information
• Owner’s Name
•Certificate Authorities Name
•Owner’s public Key
•Time Period Of Certificate Validation
Sample of Digital certificate
Advantages
• SSL provide certificate to both client and server.
• Helps to increase the business value.
• All information are encrypted so data can not be tempered.
• Give confidence in context to secure data and trustfulness of data
Constraints
• SSL providing security on point to point way , In current situation there are lot of intermediate nodes.
• In SSL, each connection requires different connection Line and certificate termination problem.
• Sometimes browser version creates the problem.
Conclusion
• SSL is the most active security agent in the era of Internet.
• From 10,0000 feet View SSL established secure channel between client and server and make synchronization between them and assure that data are passed in secure way.
