Lead study group on Identity Management

Study Group 17 has been designated the Lead Study Group for Identity Management (IdM) in accordance with World Telecommunication Standardization Assembly (WTSA-08, WTSA-12, WTSA-16) Resolution 2.

As the lead study group for Identity Management, Study Group 17 is responsible for the study of the appropriate core Questions on IdM. In addition, in consultation with other relevant study groups and in collaboration, where appropriate, with other standards bodies, Study Group has the responsibility to define and maintain the overall framework and to coordinate, assign (recognizing the mandates of the study groups) and prioritize the studies to be carried out by the study groups, and to ensure the preparation of consistent, complete and timely Recommendations.

All Study Groups are requested to keep Study Group 17 informed of their work plans regarding IdM so that they can be integrated into the overall IdM work programme.

Study Group responsibilities for IdM

WTSA Resolution 2 identifies study group responsibilities for IdM as:

  • Study Group 2: Responsible for studies relating to ensuring the consistency of the format and structure of IdM identifiers and for studies specifying interfaces to management systems to support the communication of identity information within or between organizational domains.
  • Study Group 13: Responsible for studies of functions and relevant capabilities including NGN-specific identity management functional architecture that supports value-added identity services, the secure exchange of identity information and the application of bridging/interoperability between a diverse set of identity information formats. Also to be studied are any identity management threats within the NGN and the mechanisms to counter them. In addition, Study Group 13 will study the protection of personally identifiable information (PII) in the NGN to ensure that only authorized PII is disseminated within the NGN, as well as future networks.
  • Study Group 17: Responsible for studies relating to the development of a generic identity management model that is independent of network technologies and supports the secure exchange of identity information between entities. This work also includes studying the process for discovery of authoritative sources of identity information; generic mechanisms for the bridging/interoperability of a diverse set of identity information formats; identity management threats, the mechanisms to counter them, the protection of personally identifiable information (PII) and to develop mechanisms to ensure that access to PII is only authorized when appropriate.
