A Trust-Oriented Security Model for Workflow in Business Process

摘要

Workflow in business process is becoming very popular and is being used to support many of the day to day workflows in large organizations. One of the major problems with workflow management systems is that they often use heterogeneous and distributed hardware and software systems to execute a given workflow. This gives rise to decentralized security policies and mechanisms that need to be managed. Since security is an essential and integral part of workflows, the workflow management system has to manage and execute the workflows in a secure way. At the same time, the stability and security of the virtual enterprise depends on the right balance of trust and distrust. In this paper we provide and discuss a trust-oriented security model that is grounded in business process trust characteristics. Our proposed model allows it to decide which other partners' opinions they trust more and allows partners to progressively tune their understanding of another partner's subjective recommendations.
