Identity management in a mobile service orientated grid

Abstract

Composite applications consisting of multiple mobile services require intricate service management and security infrastructures. Grid based approaches to service management can be applied to provide such infrastructures to both support and secure users and services in these composite mobile applications. The Akogrimo project has applied WSRF based Service Oriented toolkits as the core element of a mobile Service Oriented Infrastructure (SOI). Security is described in relation to the domains into which the SOI is split — Network Provider, Service Provider and two types of Virtual Organization. This paper describes how the Akogrimo SOI has been secured by an approach based on the management of identities within it. The results of this have been demonstrated initially in an E-Health scenario that is one of the first examples of a truly mobile Service Orientated Architecture.
