Editor's Notes

  1. Tutorial introduction for those with no or little familiarity with security, SSL/TLS or Public Key Infrastructures will start with basic concepts and then as the presentation progresses drill deeper into the technology since different experiences in the group how application can communicate securely over the Internet using SSL/TLS & Certificates
