Version 1.1: 03/24/2009- Conference to subclass Folder This document describes the object model for Beehive. The document does not attempt to define the model in terms of an actual programming language. Instead, we describe the model using a concise abstract notation. Once we have specified the abstract model, we will be able to define a programming language binding to the model.

Questions of belief are essential in analyzing protocols for the authentication of principals in distributed computing systems. In this paper we motivate, set out, and exemplify a logic specifically designed for this analysis; we show how various protocols differ subtly with respect to the required

Abstract. Proper authorization is essential for a QoS signaling protocol. The policy control of future QoS signaling solutions is expected to make use of existing AAA infrastructure for computing the authorization decision. In this paper, we point to two approaches for QoS authorization (based

of Authentication, Authorization, and Accounting (AAA) key management protocols. The guidance is also useful to designers of systems and solutions that include AAA key management protocols. Given the complexity and difficulty in designing secure, long-lasting key management algorithms and protocols by experts

service offered by a Mobility Services Provider (MSP). In this case, all protocol operations may need to be explicitly authorized and traced, requiring the interaction between Mobile IPv6 and the AAA infrastructure. Integrating the Authentication, Authorization, and Accounting (AAA) infrastructure

features. An important one is the infrastructure for Authentication, Authorization, Accounting, and Charging (AAAC) those mobile services. These functions will ensure that mobility will not happen into places where not authorized and will enable a commercial operation of a network, which offers services

for roadside assistance. Even though this book is not about that sort of AAA, the 3 “A”s that we talk about here, when designed properly, can bring the same peace of mind to the network operator and its customers. Authentication, authorization, and accounting are three important blocks used in the construction

, we review the "Grid problem," which we define as flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources-what we refer to as virtual organizations. In such settings, we encounter unique authentication, authorization, resource

, and notification. Service bindings can support reliable invocation, authentication, authorization, and delegation, if required. Our presentation complements an earlier foundational article, “The Anatomy of the Grid, ” by describing how Grid mechanisms can implement a service-oriented architecture, explaining how
