What is WebRTC Missing
WebRTC/IMS Chasm
Current
WebRTC
§ Security
– Identity, authentication and authorization
– More user name and passwords
– Network Denial of Service
§ Reliable network solutions
– Lose sessions on browser refreshes or network issues
– Lack of support for large networks with many sessions and many
connections
§ Interoperability
– Between networks
– Browser and devices
– Voice and video media
– Policy, charging, or internet traversal

21. Copyright © 2014, Oracle and/or its affiliates. All rights reserved. Oracle Confidential21
WebRTC Challenges: Security
Server
Telco ID Web ID
• No unified identity management
• Requires web to network
integration
• No multi-connection support
• No overload protection - DoS
• No network-level authentication
• All traffic treated the same

22. Copyright © 2014, Oracle and/or its affiliates. All rights reserved. Oracle Confidential22
WebRTC Challenge: Reliable Network Solutions
App has no Control Outside of Browser or Over the Network
AppApp
Failure! Reconnect?
App
Handover?
• Browser issues
• Refresh
• Surfing and tabs
• Network issues
• Weak signal
• Disconnects
• No network handoff

23. Copyright © 2014, Oracle and/or its affiliates. All rights reserved. Oracle Confidential23
WebRTC Challenges: Interoperability
Server
• Network:
• NAT message routing
• Slow congestive encryption
• Connections to IMS, VoIP, ..
• Browser/Device compatibility
• Poor or no codec transcoding
• Policy, charging

Attack
§ Client identity/authentication - OAuth
§ Coordinates identity across multiple sessions
§ Telco/enterprise authentication mechanisms
§ Network identity - encryption keys & network
authentication
§ Prevents network overload/DoS
§ Traffic prioritization maintains normal service
to valid users
