scope:

The present document serves as a collection of requirements and use-cases of the different stakeholders along the value-chain for the ECI Ecosystem as specified in the ECI multi-part deliverable, including specification of the architecture of the ECI system as defined in ECI specification ETSI GS ECI 001-1 (V1.2.1) [1]. An ECI Ecosystem which fulfils these requirements will reveal the following features:

A major advantage and innovation of the ECI Ecosystem, compared with currently deployed systems, is a complete software-based architecture for the loading and exchange of CA/DRM systems, avoiding any detachable hardware modules. Software containers provide a secure ("Sandbox") environment for either CA or DRM kernels, hereafter named as ECI Clients, together with their individual Virtual Machine instances. The Advanced Security System is a powerful tool for the ECI Client to enhance its security. 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 efficient protection against integrity- and substitution attacks.

The present document covers requirements details in the following clauses:

Clause 4 contains all requirements structured in clauses:

4.1 Generic Requirements;

4.2 Versatility related Requirements;

4.3 Practicability related Requirements;

4.4 ECI Client Swap related Requirements;

4.5 ECI System Security related Requirements; and

4.6 Content protection and Usage Rights Information (URI) related requirements.

Annex A deals with relevant use cases.
