Abstract The authentication mechanism in Grid need to support local heterogeneity and need to support n-way security context. The objective of this work is focused on the interoperable issue in the existing Grid Security Infrastructure. An adaptable Multi factor Authentication framework for computational grid is proposed in this work and it is compared with existing Credential Federation Systems. The proposed system is designed using the concept of Service Oriented Architecture SOA a specific type of Distributed System in which the agents are software service which are designated to perform the complicated time and resource consuming task of Credential management and Credential Validation service. GSI does not support Kerberos based authentication. Hence in order to integrate Kerberos with GSI, a Credential Translation Service CTS is designed and implemented. This feature is incorporated in this design by developing a service that can handle Kerberos token and PKI Certificate. The performance of the proposed system is compared with existing credential federation systems.

Definition Of

E-Business research and practice can be situated on following multiple levels: applications, technological issues, support and implementation (Ngai and Wat 2002). Here we consider technological components for realizing business processes and discuss their foundation architecture for technological enabling. The article provides an introduction to the terms, techniques and realization issues for eventdriven and service-oriented architectures. We begin with a definition of terms and propose a reference architecture for an event-driven service-oriented architecture (EDSOA). Possible applications in the area of E-Business and solution guidelines are considered in the second part of the article. Service-oriented Architectures (SOA) have gained momentum since their introduction in the last years. Seen as an approach to integrate heterogeneous applications within an enterprise architecture they are also used to design flexible and adaptable business processes. An SOA is designed as a distributed system architecture providing a good integration possibility of already existing application systems. Furthermore, SOA is mostly suitable for complex and large system landscapes.

The complexity and the intensity of crisis-related situations require the use of advanced distributed systems infrastructures. In order to develop such infrastructures, specific architectures need to be applied such as Component-based Modelling, Object-Oriented, Aspect-Oriented and Service-Oriented Design. This paper focuses on the use of Service-Oriented Design techniques for the development of the ATHENA Crisis Management Distributed System. The function of the ATHENA Crisis Management Distributed System is based on the use of data generated by social media for the evaluation of the severity of the conditions of a crisis and the coordination of the appropriate measures in response to the crisis. The paper presents a new definition for Service-Oriented Architecture (SOA) and specifies the benefits that are generated by the use of this new definition in the development of the ATHENA system. Useful conclusions are also drawn in relation to how the definition considers the different technical backgrounds of users.

Definition Of

Considering the lack of resources in health centers located in rural zones, a part of Colombian population goes affected by the quality of the health Service received. If this is added the low level socioeconomic of some rural population, it is generated a geographic vulnerability. For that reason in this work is presented a Service Oriented Architecture that has as objective support health centers with low technical resources with technology that allows a physical rehab attention independently of the localization of patient and health professional. By way of this, a distributed system it is proposed, using a dispersed communication media like the internet. It is planned to make a modeling process based on a formal tool like the Petri Nets to assure the definition of the services, assistant dispositive teleoperation and the integration and coordination of the system.
