Trigon Based Authentication Service Creation with Globus Middleware

A Grid allows its constituent resources to be used in a coordinated fashion to deliver various qualities of service, relating for example to response time, throughput, availability, and security, and/or co-allocation of multiple resource types to meet complex user demands, so that the utility of the combined system is significantly greater than that of the sum of its parts. Security is a major concern as a grid enables sharing of valuable resources and sensitive information across heterogeneous users. Authentication, message integrity and confidentiality are the major concerns in grid security. The proposed approach uses a trigon based authentication and authorization of the grid entities. Grid service is stateful and transient web service, which can be invoked by clients, and is considered to be the mainstream of future internet. A service is defined by identifying sequences of specific message exchanges that cause the service to perform some operation. By thus defining these operations only in terms of message exchange, we achieve great flexibility in how services are implemented and where they may be located.The creation of Web Services standards is an industry-led initiative, with some of the emerging standards in various states of progress through the World Wide Web Consortium (W3C). The security protocol has been implemented and tested using Globus middleware. To achieve reuse of behaviors of this authentication concept, operations are often grouped together to form a SHA based authentication service using prerequisites as build.xml , globus-build-service.sh, WSDL file and globus as middleware.
