A secure environment for grid-based supply chains

This paper introduces a transportation supply chain which exploits Grid services for optimizing both the delivery and cost of each customer order. The proposed case study focuses on an auction-based model to select transporters for given transportation tasks in a generic supply chain. Each transporter uses a Grid-based computing service to re-optimize the routes of its vehicles after the addition of each new transportation task. The main objective of this paper is to describe a secure environment for the transportation supply chain by identifying its security issues and developing security components that help to solve these issues. These components are currently under implementation in the EU GridTrust project.
