Trust Brokering and Its Use for Resource Matchmaking in Public-Resource Grids

Abstract

This paper presents a trust brokering system that operates in a peer-to-peer manner. The network of trust brokers operate by providing peer reviews in the form of recommendations regarding potential resource targets. One of the distinguishing features of our work is that it separately models the accuracy and honesty concepts. By separately modeling these concepts, our model is able to significantly improve the performance. We apply the trust brokering system to a resource manager to illustrate its utility in a public-resource Grid environment. The simulations performed to evaluate the trust-aware resource matchmaking Dr Azzedin contributed towards the work in this paper while he was at strategies indicate that high levels of 'robustness' can be attained by considering trust while matchmaking and allocating resources.

Design and Comparative Analysis of MCDM-based Multi-dimensional Trust Evaluation Schemes for Determining Trustworthiness of Cloud Service Providers

“…Azzedin et al [18] proposed a trust brokering model that uses the concept of trust brokers and operates in peer-to-peer manner by providing peer recommendations. The model is intended to be used in public-resource grid systems.…”

“…Though there are other similar works [18][19][20][21][22][23], which also evaluate trustworthiness of a CSP, but they do not establish trustworthiness based on compliance of a CSP to SLA, which, we argue, is very necessary to truly label a CSP as trustworthy or untrustworthy as per trustworthiness definition defined earlier. Moreover, most of the approaches work with subjective attributes which are difficult to quantify and not easy to work with in real practical scenarios.…”

A Hybrid Model for Load Aware Trust Management in Grid

“…Hence in this account, the individual dimension is taken to be a product of value in IDT and decay function (Azzedin et al, 2006):…”

“…Related work: Trust is defined as the firm belief in the competence of an entity to act as expected such that this firm belief is not a fixed value associated with the entity but rather it is subject to the entity's behavior and applies only within a specific context at a given time (Ma et al, 2006;Azzedin et al, 2006). The firm belief value will be in the range of maximum and minimum trust values.…”

Feedback behavior and its role in trust assessment for peer-to-peer systems

“…One way to address this problem is to establish trust through reputation. The reputation concept is already used in many trust models [1,4,18,28], where peers can rely on others for information pertaining to a specific peer. The idea of ensuring adequate level of trust when information are exchanged in ubiquitous applications lead us to the focus of this paper, namely trust, which is one of the major challenges in the field of ubiquitous computing.…”
