Objectives
• To describe the NSTIC ID Ecosystem focusing on
the interactions between members of an “Online
Community”*
• To describe how major NSTIC Strategy Document
elements work together to define an ID Ecosystem
and its participants
2013
3
* The “Online Community” is central to the NSTIC ID Ecosystem concept

Context
• This „conceptual model‟ sits above items such as
standards, use cases, functional models
• The intent is to offer a view of what the target
state ID Ecosystem might look like and give
structure to the components of the NSTIC ID
Ecosystem
2013
4

The NSTIC ID
Ecosystem*
will consist of
different online communities
that use
interoperable
technology, processes, and policies
2013

*Source: The NSTIC Strategy
Document

Take-away Concepts
• A defining characteristic of the ID Ecosystem is
that it is comprised of “online communities”
interacting in a variety of ways
2013
6

NSTIC Vision*
Individuals and organizations
utilize secure, efficient, easy-to-use and
interoperable identity solutions
to access online services
in a manner that
promotes confidence, privacy, choice, and
innovation.
2013
7
Document

Take-away Concepts
• Access to online services is the central concept of
the Vision
• “Identity Services” enable access to online
services
• The online services and identity services must
have features and capabilities that encourage
adoption and use, and mitigate concerns and
barriers to acceptance
2013
8

Trust Framework*
• developed by a community
• defines the rights and responsibilities of that
community‟s participants
• specifies the policies and standards specific to the
community
• defines the community-specific processes and
procedures that provide assurance
• considers the level of risk associated with the
transaction types of its participants
2013
9
Document

Take-away Concepts
• The online community sets their own policies,
standards and rules around the transactions and
interactions of their members
2013
10

In A Nutshell
• Online Communities set their own rules according
to their members‟ needs
• Online Communities interact with each other in the
ID Ecosystem
• The rules of different Online Communities may be
different
• Access to online services enabled by identity
solutions is at the heart of the ID Ecosystem
2013

ID Ecosystem
Framework
Rules

Take-away Concepts
• Online Communities „inside the line‟ have been
evaluated against the ID Ecosystem Framework
policies, standards and rules
• These communities meet the conditions of inclusion
• The nature of the inter-community interactions is
currently unknown and undefined (?)
• Although there are Online Communities outside
the NSTIC ID Ecosystem, they are not shown
here
2013
13

Online Community
• Take a closer look at the internal structure of an
“Online Community”
2013
14

A Proposed Point of View
• Within an Online Community, think of „Access to Online
Services‟ as an interaction or transaction between a
provider and consumer of that online service
• The provider, consumer and service must abide by the rules
of the Online Community – the Trust Framework rules
• The online service consumer can choose which providers
and services (and Communities!) meet their needs, including
privacy, security, reliability, ease of use, confidence, etc.
• The online service provider defines what an online service
consumer must do in order to receive service – the “Terms of
Service”
• Some terms might be satisfied by presenting third-party credentials
or tokens; or by payment; or by group affiliation or membership
2013
15

The „Transaction‟
Point of View
In this point of view the working unit is
the interaction/transaction
between provider and consumer
plus the Terms of Service
plus the Fulfillment of those terms
meeting the community‟s Trust Framework rules
– all else exists to support this interaction

Where‟s the IdP?
• For that matter, where‟s the CSP, CA, IdP/V, RP
and all the other Assurance, Trust and Identity
bits?
• This conceptual model considers them to be the
means by which Terms of Service are expressed
and fulfilled – so they do not appear at this level of
abstraction
2013

The “Online Community”
2013
19
The Community
• Shared values, beliefs, principles
• Common goals and objectives
• Has „tools‟ for joining
• Has „tools‟ for locating
• Could be mandated by law
The Transaction
• A particular set of commercial,
social, „social contract‟, or
information exchanges that exist
for the community, in support of
their common goals
Business
• Shared need to perform
transactions in the context
of the community
Legal
• Trust Framework
agreements
• Commercial contracts
• Legal Framework
Technical
• Protocol suites & capability
• Network Connectivity
• Shared Standards
The Online Community
Trust Framework Rules

• The provider states the “Terms of Service” for
transacting or interacting with their online service
• The Terms must comply with the Online Community
Trust Framework Rules, including accessibility,
privacy, security, etc.
• The individual/consumer chooses which providers
to interact with, in part based on the Terms offered
“Terms of Service”
2013
20

Identity Services
• Imagine some possible Terms of Service:
• “Give me these attributes, cryptographically signed by an
Attribute Provider I recognize, so I can verify your
eligibility”
• “Prove that you have authenticated successfully with an
IdP I have a trust relationship with”
• “Prove that you did the authentication with a Level 4
Credential”
• That’s where they are – the „typical‟ Identity Services
are support mechanisms to enable Terms that
leverage third party identity and credential services
2013
21

Some Examples of “Terms”
Business
• Payment / Money
• Information
• Eligibility
Legal
• Contract /
Agreement
• Terms and
Conditions
• Lawfulness
Technical
• Protocols &
Standards
• Crypto capability
• Electronic Tokens &
Credentials
• Other technical
capabilities
2013
22

Entering the Ecosystem
• Online Communities become formal participants in
the NSTIC ID Ecosystem through an Accreditation
Program
• The Accreditation Program is being designed by
teams in the IDESG
• The Accreditation Program will be documented
within the ID Ecosystem Framework
2013
23

ID Ecosystem
Framework*
the overarching set of
interoperability standards,
risk models,
privacy and liability policies,
requirements, and
accountability mechanisms
that structure the Identity Ecosystem
2013
24
Document

Accreditation
• IDESG, via the Accreditation Authority:
• Assesses the Online Community and its participants
against that Online Community‟s Trust Framework
(Operating Rules)
• Confers Trustmarks to signal to participants that
Assessments and Accreditation has been done to a
known standard
2013
25

Accreditation Authority*
assesses and validates
identity providers,
attribute providers,
relying parties,
and identity media,
ensuring that they all adhere
to an agreed-upon trust framework
(the community’s trust framework)
2013
26
Document

Trust Framework*, redux
• developed by a community
• defines the rights and responsibilities of that
community‟s participants
• specifies the policies and standards specific to the
community
• defines the community-specific processes and
procedures that provide assurance
• considers the level of risk associated with the
transaction types of its participants
2013
27
Document

Interoperable?
• Interoperability within an Online Community is a
defining feature of Online Communities
• IDESG could foster technology, process and
policy interoperability between Online
Communities by defining common Accreditation
Patterns for the inter-Community interactions
• IDESG, via the Accreditation Authority, could
assess and issue Trustmarks for the inter-
Community interactions
2013
28

Recap
• Online communities set their own rules according to their
members‟ needs
• Online communities interact with each other in the ID
Ecosystem
• The rules of different Online Communities may be different
• Access to online services enabled by identity solutions is at
the heart of the ID Ecosystem
• IDESG serves to establish the ID Ecosystem Framework
and Programs needed to identify and evaluate Online
Communities seeking to participate in the NSTIC ID
Ecosystem

Next Steps
• Develop narrative scenarios that explain what an individual might
experience when seeking services or engaging with a provider of
services
• Refine the concept of „Terms of Service‟
• Develop examples that explain how this new concept relates to real-world
implementations
• Define the nature of „interoperable interactions‟ between Online
Communities
• What policy, protocol, technology or practice conditions must exist in order to
be considered „interoperable‟?
• Relate the conceptual model to other IDESG work products
• How does this model fit the work already completed in Standards, Security,
Privacy, Functional Model, etc?
