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
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
