Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). ETSI ETSI TR 187 013 V3.1.1 (2011-02) 71 Scope The present document presents the result of a study

29、 of options for the IPTV security architecture supporting TISPAN NGN Release 3 that satisfies the security requirements for IPTV given in TS 187 001 i.1. The present document offers the results of analysis of the options for security architecture and mechanisms to provide IPTV service protection whe

30、re service protection refers to the protection offered during the period when IPTV media is transmitted in the NGN. A security architecture for a general content protection framework to allow comparison of existing content protection solutions (e.g. DRM systems) is required for the NGN, but is not c

31、overed by the present document. Content protection includes the provision of post-delivery protection of IPTV media and may include controls to ensure that the user can only use the content in accordance with the license it has been granted, e.g. the times of the content can be viewed. NOTE: The fun

32、ctional architecture for IMS based IPTV without security entities conforms to TS 182 027 i.5. The functional architecture for dedicated IPTV subsystem without security entities conforms to TS 182 028 i.6. 2 References References are either specific (identified by date of publication and/or edition n
