Study Group 17 is the Lead Study Group on:
● Security
● Identity
management (IdM)
● Languages and description techniques
 A study group may be designated by WTSA or TSAG as the lead study group
for ITU-T studies forming a defined programme of work involving a number
of study groups.
 This lead study group is responsible for the study of the appropriate core
Questions.
 In addition, in consultation with the relevant study groups and in
collaboration, where appropriate, with other standards bodies, the lead
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.
* Extracted from WTSA-12 Resolution 1
15/58
SG17 is “Parent” for Joint Coordination Activities (JCAs) on:
● Identity management
● Child
online protection
 A joint coordination activity (JCA) is a tool for management of the work
programme of ITU-T when there is a need to address a broad subject
covering the area of competence of more than one study group. A JCA
may help to coordinate the planned work effort in terms of subject matter,
time-frames for meetings, collocated meetings where necessary and
publication goals including, where appropriate, release planning of the
resulting Recommendations.
 The establishment of a JCA aims mainly at improving coordination and
planning. The work itself will continue to be conducted by the relevant
study groups and the results are subject to the normal approval processes
within each study group. A JCA may identify technical and strategic issues
within the scope of its coordination role, but will not perform technical
studies nor write Recommendations. A JCA may also address coordination
of activities with recognized standards development organizations (SDOs)
and forums, including periodic discussion of work plans and schedules of
deliverables. The study groups take JCA suggestions into consideration as
they carry out their work.
* Extracted from Recommendation ITU-T A.1
16/58
ITU-T Joint Coordination Activity on Identity Management
(JCA-IdM)



Coordinates of the ITU-T identity management (IdM) work.
Ensures that the ITU-T IdM work is progressed in a well-coordinated way between
study groups, in particular with SG2, SG13 and SG17.
Analyzes IdM standardization items and coordinates an associated roadmap with ITUT Q10/17.
Acts as a point of contact within ITU-T and with other SDOs/Fora on IdM in order to
avoid duplication of work and assist in implementing the IdM tasks assigned by
WTSA-12 Resolution 2 and in implementing GSC-16 Resolution 4 on identity
management.
In carrying out the JCA-IdM’s external collaboration role, representatives from other
relevant recognized SDOs/Fora and regional/national organizations may be invited to
join the JCA-IdM.
Maintains IdM roadmap and landscape document/WIKI.



IdM is a security enabler by providing trust in the identity of both parties to an e-transaction
IdM also provides network operators an opportunity to increase revenues by offering
advanced identity-based services
The focus of ITU-T’s IdM work is on global trust and interoperability of diverse IdM
capabilities in telecommunication.
Work is focused on leveraging and bridging existing solutions
This Question is dedicated to the vision setting and the coordination and organization of the
entire range of IdM activities within ITU-T
Adoption of interoperable federated identity frameworks that use a variety of authentication
methods with well understood security and privacy
Encourage the use of authentication methods resistant to known and projected threats
Provide a general trust model for making trust-based authentication decisions between two
or more parties
Ensure security of online transactions with focus on end-to-end identification and
authentication of the participants and components involved in conducting the transaction,
including people, devices, and services
