Augmentation to GT4 framework for B2B collaboration over grid

We propose a framework for secure and trusted business to business (13213) collaborations over grid. The core of the proposal consists of a centralised rating system for assignment and maintenance of trust and reputation scores of enterprises. We also propose augmentations to the Globus Toolkit 4 (GT4) [8] for implementing the proposed rating system. It involves integration of three functionalities, namely, (i) building a suitable token structure according to the model of a security token, (ii) building and deploying a trust service which keeps track of the ratings of the collaborating business entities, and (iii) building an information aggregator source which provides these ratings and related information from the trust service to the GT4 default index service.
