The goal of WebRTC IMS Client access to IMS is to significantly expand the pool of clients able to access 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 WebRTC IMS Client access to IMS.

For this purpose the present document is addressing:
  • WebRTC IMS Client authentication mechanisms, including the re-use of existing IMS authentication mechanisms from WebRTC IMS Clients;
  • Required enhancements to IMS media plane security;
  • Control plane security related aspects.
