“…Previous work has examined the use of Trust Management in providing a security architecture within the WebCom metacomputing environment [8]. WebCom provides support for heterogeneous applications, potentially made up of such web service/middleware technologies as EJB, COM (.NET) and Grid middlewares, such as Globus.…”

Supporting security in distributed systems is becoming more important with the ongoing work in grids, distributed middlewares and web services. Decentralised security architectures allow the stakeholders in these distributed computations, the providers of both compute resources and the applications executing on them, to have a say in how a computation progresses. One of the most important issues in creating authorisation policies is how the components of these distributed applications are named. Providing a consistent and flexible naming architecture allows more fine-grained and usable security policies to be created and enforced.This paper introduces the naming architecture for the WebCom system. This architecture supports the addressing of all required information, with as much precision as is needed to create sophisticated authorisation policies.

Abstract. Access control in distributed systems has been an area of intense research in recent years. One promising approach has been that of trust management, whereby authentication and authorization decisions are combined in a unified framework for evaluating security policies and credentials. In this paper, we report on our experience of the past seven years using the PolicyMaker and the KeyNote trust management systems in a variety of projects. We start with a brief overview of trust management in general, and KeyNote in particular; we describe several applications of trust management; we then discuss various features we found missing from our initial version of KeyNote, which would have been useful in the various applications it was used. We conclude the paper with our plans for future research.

“…The default security architecture in WebCom utilises the KeyNote trust management system to ensure only authorised clients are scheduled secured components [28], [29]. Providing support for either reputation based or monetary based metrics becomes a matter of performing additional authorisation checks.…”

“…Applications are coded as hierarchical graphs which provide a simple notation in which lazy, eager and imperative computation can be naturally expressed. A Secured WebCom environment [28] uses KeyNote to help manage the trust relationship with other Secured WebCom environments. A WebCom environment [33], [34], [35] (Figure 9) is made up of several modular components: Execution Engine Modules, Connection Manger Modules, Load Balancing Modules and Security Manager Modules.…”

“…The WebCom system [28], [29], [30] is a distributed secure and fault-tolerant architecture that can be used to coordinate the distributed execution of functional components across a network. The system uses implicit program parallelism, separates the application program from the underlying computation engine and is efficient yet compact.…”

Administration of Grid resources is a time consuming and often tedious job. Most administrative requests are predictable, and in general, handling them requires knowledge of the local resources and the requester. In this paper we discuss a system to provide automated support for administrative requests, such as resource reservation and user account management. We propose using trust metrics to help judge the merits and suitability of each request. We outline how these metrics can be implemented using trust management techniques into a practical system we call GridAdmin.
