Study on security enhancements to Web Real Time Communication (WebRTC) access to IP Multimedia Subsystem (IMS)
The present document contains a study on security issues following the potential modifications of the IMS architecture and stage 2 procedures as required by the support of eWebRTCi (Enhancements to WEBRTC interoperability).
In particular, the present document focuses on:
• Support for end to end WebRTC security, subject to regulatory constraints, that avoids conversion between WebRTC and IMS security protocols , including the feasibility of end to end security aspects
• Third-party WebRTC access in the case where the 3rd party allocates IMS identities from a block where the associated subscription corresponds to a class of users supported by the WebRTC environment (e.g., enterprise associates) rather than a single end user
