Foreword This Group Report (GR) has been produced by ETSI Industry Specification Group (ISG) Embedded Common Interface (ECI) for excha

24、ngeable CA/DRM solutions. The present document on Guidelines for the implementation of ECI complements ETSI GS ECI 001 (all parts), i.1 to i.7 for the Embedded Common Interface for exchangeable CA/DRM solutions Group Specification (GS). NOTE: The use of terms in bold and starting with capital charac

25、ters in the present document shows that those terms are defined with an ECI specific meaning, which may deviate from the common use of those terms. Modal verbs terminology In the present document “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted

26、as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions). “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. Introduction Service and content protection realized by Conditional Access (CA) and Digital Rights Ma

27、nagement (DRM) are essential in the rapidly developing area of digital Broadcast and Broadband services. This includes the distribution of HD and UHD content to various types of customer premises equipment (CPE) in order to protect business models of content owners and Service providers, including B

28、roadcasters and PayTV operators. Existing CA/DRM technologies limit the freedom of many players in digital multimedia content markets. Due to technological progress, innovative, software-based CA/DRM solutions become feasible. Maximizing interoperability while maintaining a high level of security, t

29、hese solutions promise to meet upcoming demands in the market, allow for new businesses, and broaden consumer choice with respect to content consumption via broadcast and broadband connections. ETSI ETSI GR ECI 004 V1.1.1 (2018-03)6An ECI Ecosystem, compliant with ETSI GS ECI 001 (all parts) i.1 to

30、i.7, addresses important attributes, such as enabling a high level of system security, flexibility and scalability due to software-based implementation, as well as exchangeability fostering a future-proof solution and enabling innovation. Further aspects are applicability to content distributed via

31、different types of networks, including classical digital broadcasting, IPTV and OTT Services. The ECI system specification of an open eco-system, fostering market development, provides the basis for exchangeability of CA and DRM systems in CPEs, at lowest possible costs for the consumers and with mi

32、nimal restrictions for CA or DRM vendors to develop their target products for the PayTV market. Complementing ETSI GS ECI 001 (all parts) i.1 to i.7, the present document gives further guidance and addresses beside necessary performance requirements a number of use cases and scenarios, which on one

33、side make use of the ECI Ecosystem and on the other extend its possibilities. ETSI ETSI GR ECI 004 V1.1.1 (2018-03)71 Scope The present document serves as a guidance document for the ECI Ecosystem as specified in ETSI GS ECI 001 (all parts) i.1 to i.7, including specification of the architecture of

34、the ECI system as defined in ETSI GS ECI 001-1 i.1 and specification of the requirements as defined in ECI Group Specification ETSI GS ECI 001-2 i.2. A major advantage and innovation of the ECI Ecosystem, compared with currently deployed systems, is a fully software-based client container architectu

35、re, backed by a standardized advanced security hardware and secure software functionality for the loading and exchanging of CA/DRM client systems in CPEs. ECI compliant solutions do not require any detachable hardware modules in CPEs. Software containers provide a secure (“Sandbox“) environment for

36、either CA or DRM kernels, hereafter named as ECI Clients, together with their individual Virtual Machine Instances. The download process is embedded in a secure and trusted environment, providing a trust hierarchy for installation and exchange of ECI Host and ECI Clients and thus enabling an efficie

37、nt protection against integrity- and substitution attacks. For this reason, the ECI Ecosystem integrates an advanced security mechanism. The present document covers implementation guidance details in the following clauses: Clause 4 contains performance requirements and parameters for the ECI Host, t

38、he ECI Client, the Virtual Machine and for the Advanced Security System. Clause 5 deals with use cases and applications based on the ECI Ecosystem, which either complement the ECI multi-part Group Specification or address given scenarios in more detail. The present document has the objective to make

39、 available to ECI implementers as much as possible of the common understanding captured during the work of the ISG ECI developing the ECI specification series i.1 to i.8. The present document was prepared with the intention to provide know-how complementary to the content of the ECI specifications i

40、.1 to i.8 itself and about the environment in which an ECI Ecosystem will be operated. It is planned to extend this guideline by further guidance and background information gained during the implementation and operation of ECI compliant ecosystems. 2 References 2.1 Normative references Normative ref
