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

  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.
