Enterprises

Organizations that, as part of your belonging, help you manage your information and access in an electronic world We may use three or so enterprises…

  • Work – your university or your corporation
  • Home – a service provider offering consumer

services

  • Personal – a second service provider for extra

privacy and security

Enterprise Middleware

Identity Services – converting real identities to electronic identities Authentication – verifying an electronic identity Directories – containing the attributes of identity and systems Authorization – deciding what actions an identity is permitted to do

Federations of Enterprises

An interrealm approach – enterprises are realms, and they mutually join into federations to conduct business. For the consumer marketplace, users subscribe to commercial service offerings to interact with business federations; enterprises that might

  • ffer consumer services include desktop OS’s

(Microsoft), ISP’s (AOL), Telecoms (Nokia, telco’s), consumer product vendors (Ford, United Airlines) and banks (Chase).

Emergent Federations

SecuritiesHub – 8 large banks to share research reports among customers Swiss R&E Federation – national universities using Shibboleth InCommon – universities Club Roadkill – experimental testbed Liberty Alliance, Federated .NET, Shibboleth, PAPI are among the tech drivers…

Clusters of Federations

Federations of similar interests or communities. Share metadata, attribute standards May have dissimilar trust and policy issues Clusters of federations may resemble groups of NRENs, perhaps with different participants

What could go wrong? …how we could fail A single vendor wins A marketplace does not get established Users don’t care about privacy or security Federations prove costly and difficult Inter-federation issues do not get solved International issues prove intractable

What could go wrong …if we succeed Erosion of privacy

  • Difficulty Exposure Rubber squeeze toys

Lost time in the management of collaboration

  • Modalities Complexities Global issues

Issues and turtles

The Bertrand Russell turtle

  • will the layers get to be too much
  • will the complexity be manageable by users

The Edward Oppenheimer turtle
