Design of a framework for handling security issues in grids

Grid Computing has emerged as core computing technology in many distributed applications initiated by different organizations all over the world. It aims to enable large scale resource sharing. Security is a big and challenging issue as a grid service may impact number of other services/resources distributed over wide area - networks. The dynamic and multi-institutional nature of grid applications introduces challenging security issues that require new technical approaches. This paper proposes, at an abstract level, a framework for handling security issues in grids. The framework is capable of addressing both, generic as well as application specific security issues of grid services.
