What’s the Problem?ShibbolethFederationsInCommon Federation
2
Multiple usernames and passwords for users Multiple copies of personal data held by third
parties Duplication of effort across multiple institutions Service and resource providers having to
interface with multiple systems Difficulty in sharing resources between
institutions Anytime, anywhere access to resources Compliance with legislation (FERPA, GLB…)
Scaling Enabling identity holder to authenticate Enabling service provider to control
authorization Providing security and privacy Ensuring accuracy and timeliness of
account and identity data
Internet2 partnered with Middleware Architecture Committee for Education (MACE)◦Leading international identity architects
Ongoing work in the great challenges of digital identity◦Extending access beyond an organization to
facilitate ease of use and collaboration while maintaining security and privacy Shibboleth Single Sign-on and Federating Software InCommon Federation
◦Among other things….
7
Open source standards-based web single sign-on package (supports SAML v1.1, SAML v2)
Supports the Federated Identity model◦ Identity Provider (IdP) authenticates the browser
user and provides Attribute Assertions describing the user
◦Service Provider (SP) validates the Assertions, makes an Access Control decision, and provides Resources
◦Each player identified by a unique entityID value
Leverages local identity management system
8
Enables access to both campus and external applications
Protects users’ privacy Helps your service partners Integrates well with other SAML2
software Adoption by 20+ other Higher
Education/Research federations around the world
9
Access Application/Service Provider Site Identify Home Site Redirect to Home Site Shibboleth IdP Authenticate locally IdP determines which attributes to
release Redirect back to Application, carrying
Attribute Assertions SP site uses Assertions to determine
access rights, and to personalize
Identity isn’t always released◦Elsevier Science Direct – license number and
opaque identifier for personalization (optional)◦Microsoft Dreamspark – affiliation◦Apple iTunesU – course number
But identity is needed by some◦WebAssign – name and course number
Defined in eduPerson schema and increasingly elsewhere

Service ProvidersThe Challenging Way
A group of member organisations who agree to a set of rules
An independent body managing the trust relationships between members
End user organisations ◦ Act as identity providers (IdPs) and optionally service
providers (SPs)◦ Authenticate end users◦ Release information (attributes) about individuals to
service providers Service and resource providers (SPs)◦ Accept information (attributes) and use to authorize (or
not authorize) access
Common data/Attributes to exchange Shared technology, policy, process◦Rules of engagement◦ Information about how to connect◦Specifies accuracy, integrity, and use of
attributes◦Problem resolution
Registration mechanism for members Maintain member information Trouble shooting, ongoing development

The Role of the Federation
1. Agreed upon attribute vocabulary & definitions: member of, role, unique identifier, courses, …
2. Criteria for identity management practices (user accounts, credentialing, etc.), privacy stewardship, interop standards, technologies
3. Trusted exchange of participant information
4. Trusted “notary” for all universities and partners

135 members representing 2.8 million individuals.◦ 96 higher education institutions,◦ 6 government agencies or non-profit laboratories, and ◦ 33 corporations (public and non-profit)
Agree to a common participation agreement that allows each to inter-operate with the others
InCommon sets basic practices for identity providers and service providers. ◦ Focus so far on campus identity management processes
and attributes

Ease user account management Higher security Privacy maintained Greatly reduced integration work for each
service provider Policy driven release of identity Emerging tools provide option for user
consent in real time, as attributes are released
Standards
Accurate implementation of licence conditions Users take better care of credentials Organizations take better care of assertions Information about individuals always up to
date◦Authentication is performed by the IdP◦Can authorize just-in-time per institution, role,
and/or entitlement or other characteristic Reduced user support requirements
Used by InCommon to exchange attribute information
Standard schema used in identity management systems across HE, not just in InCommon
Defined by MACE-Directories working group
New needs arising as service providers diversify
