In the relation of workflow and trust characteristics, and requirements in service workflows

Abstract

Service-based interactions have become common over the past few years. Nowadays, their applications are visible in several forms including e-commerce, Virtual Organizations, Grid, and Cloud Computing. Proliferation of services leads to the creation of new value-added services composed of several sub-services in a pre-specified manner, known as service workflows. One important challenge is how to ensure security from the viewpoints of both workflow owners and participating services; each of which possesses its own requirements. Although there are a number of proposals regarding this, the comprehensive trust and security requirements are still immature. The intuition to develop a solution generic to service workflows is that workflow and trust characteristics must be incorporated. This article studies on the relationship of workflow characteristics with respect to trust, and then trust and security requirements for service collaborations are synthesized. © 2011 Springer-Verlag.
