Report Activities
  • Modern University educational resources
    organization and an access management
  • Analysis of worldwide activities, principal
    directions
  • Concept of software model for
  • intra-university and inter-universities
    education support.

3
Report Main Tasks
  • To analyze a main set of web-oriented virtual
    services which need to be accessible for modern
    (virtual) university students and staff.
  • To analyze and to determine principal points in
    line
  • to design of virtual university software
    architecture.
  • To analyze progressive worldwide solutions for
    above items.
  • To make recommendations.

5
Principal Points in Line to Design of Virtual
University Software Architecture.
  • A Single Sign-On authentication via Web for every
    user to all distributed restricted educational
    resources.
  • Web authorization for every user to access all
    distributed restricted educational resources.

6
Definitions
  • Authentication a registration of user for an
    access to resource as usually with login and
    password or other identifiers smart-cards,
    certificates, etc.
  • Authorization assignment of different rights
    for every user to access a resource (i.e.
    student, tutor, administrator, etc.)

7
Why these Principal Points are Selected
  • - Individual authentication and authorization
    for an every educational
  • resource
  • requires
  • -a lot of different logins and passwords for
    every user
  • -a lot of logins and passwords for all
    users
  • -administrators complicated support
  • -a lot of repositories
  • creates problems
  • -with inter-institutional and
    intra-institutional access to educational
    resources
  • -with development of e-learning using
    inter-institutional links
  • -with a virtual university organization

8
What well get
  • -a single login and password for user to access
    all educational resources
  • -easy inter-institutional and intra-institutional
    access to resources
  • -transparent organization of e-learning using
    inter-institutional links

Internet2IBM ProjectShibboleth WebISO model
Open Source software oriented
Shibboleth is a web-based inter-institutional
Single Sign-On (SSO) authentication and
attribute exchange mechanismfor an access to
educational resources. WebISO is a web-based
intra-institutional SSO authentication for an
access to educational resources
Shibboleth joints 262 Universities in the U.S.A.
A-Select (compatible with Shibboleth) has 150,000
users in higher education of the Netherlands in
2005
currently

10
A-Select
  • A-Select uses as a standard authentication
    platform in the Netherlands. There is designed
    initially as a commercial product. From 2004
    A-Select is open source.
  • Compatible with Shibboleth.
  • There are three product lines
  • A-Select Basis (a continuation of the
    current implementation)
  • A-Select Components (additional
    functionality such as attribute acquisition and
    authorisation)
  • A-Select Next Generation (NG) - research
    and development of the new A-Select platform.

Shibboleth Federation(definition)
  • Shibboleth federation - is a group of
    organizations (universities, corporations,
    content providers, etc.) who agree to exchange
    attributes using the Shibboleth protocols.
  • As a rule, it has links to SSO and AA (Attribute
    Authority) of registered organizations.

    Federation was done for UIITE and experiences
    with Shibboleth under InQueue support are started.

32
What we plan
  • To start experiences with completely shibbolized
    e-learning platform OLAT
  • To use UIITE LDAP repository for experiences with
    Shibboleth
  • To create a local Shibboleth Federation for test
    purposes on a base of UIITE
  • To learn possibilities of Netherlands National
    system A-Select at Delft Technical University
    during a visit to Delft from Feb.18 through March
    05, 2006.

Conclusion
  • Shibboleth (Internet2IBM) project may be
    recommended as a basic for development of virtual
    university architecture or any other distributed
    web-oriented educational organization
  • Shibboleth allows to use web-based Single Sign-On
    (SSO) for Inter-Institutional and
    Intra-Institutional access to educational
    resources and facilitates all procedures for
    modern education support
  • Shibboleth is supported by modern commercial
    e-learning platforms
  • Shibboleth is oriented for using of open source
    software
  • Shibboleth allows to use different types of
    distributed architectures for web-oriented
    learning
  • Shibboleth is most progressive technology in line
    to education support in modern university or any
    virtual university.
