1. SSL(Secure Socket Layer) Guided By:- Presented By:- Richard Sinn Jimmy Mehta 005239638

2. Agenda Introduction Objectives of SSL Protocols in SSL Working of SSL Working of Digital Certificate and Public Key in SSL Constraints and Advantages Conclusion

3. Introduction SSL mainly used for providing security on Web. It is originally developed by Netscape. Use Key algorithm and Digital Signature Public Key Algorithm Private Key Algorithm Verisign and Geotrust plays the role of Digital Certificate Provider SSL gives security Assurance to both Party(Client and Server)

4. Objectives Authentication of Client and Server Ensure Data Integrity Securing Data Privacy

5. Protocols working under SSL 1 ---- Handshake Protocol 2 ---- Record Protocol 3 ---- Alert protocol Client Server 1 2 3

6. Working Of SSL

7. 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

8. Sample of Digital certificate

9. 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

10. 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.

11. 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.
