Project Description |
Organizations are increasingly using the Internet and Grid to offer
their own services and to utilise the services of others. Presence
of a wide variety of services and resources creates new
opportunities for providing value added, inter-organizational
services by composing multiple existing services into new Composite
Services (CSs). This naturally leads to resource sharing across
organizational boundaries. An inter-organizational business
relationship is commonly referred to as a virtual organization (VO).
Whether in the context of large-scale scientific experiments or
eCommerce, eGovernment or any other collaborative effort,
organizations need cost-effective ways of finding, purchasing and
managing services performed by other organizations. It is therefore
necessary for organizations to be able to set-up and manage business
links with other organizations in a rapid, dynamic and flexible
manner. However Virtual Organisations blur the distinction between
outsiders and insiders, yet organizations forming a VO wish to
preserve their individual autonomy and privacy. A central problem in
VO management therefore concerns how organizations can regulate
access to their resources by other organizations in a way that
ensures their individual policies for information sharing are
honoured. Regulating access to resources by other organizations is
difficult because the organizations might not trust each other.
Organizations will therefore require that their interactions with
other organizations be strictly controlled and policed.
