TUX - TMS : Thapar University Extensible - Trust Management System
نویسنده
چکیده
In a Grid Computing scenario, where the market players are dynamic; traditional assumptions for establishing and evaluating trust, do not hold good anymore. There are two different methods for handling access controls to the resources in grids: first by using policy based approach; where logical rules and verifiable properties are encoded in signed credentials and second by using reputation based approach; where trust values are collected, aggregated and evaluated to disseminate reputation among the market players. There is a need for dynamic and flexible general-purpose trust management system. In this paper TUX-TMS: an extensible reputation based Trust Management System is presented for establishing and evaluating trust in grid systems.

Study of Verification of the Reputation Scaling Module of Trust Management System
The trust management system (TMS) developed through this research effectively implements a decentralized access and permission management scheme. The Reputation Scaling module (RSM) was the heart of the TMS. Our Reputation Scaling module applied different levels of trust to reports and observations. RSM advanced the current state of the art by introducing a reputation scaling mechanism that mai...
متن کاملTrust Aware Data Aggregation and Intrusion Detection System for Wireless Sensor Networks
Data Aggregation (DA) is one of the most frequently used techniques in Wireless Sensor Networks (WSNs) to improve the network lifetime. It involves gathering, consolidating, and routing the sensory data collected by sensor nodes. However, research studies have demonstrated that the dependability of the DA process affects severely when malicious nodes are present in the network. Many security so...
متن کاملUser Requirements Model for University Timetable Management System
Automated timetables are used to schedule courses, lectures and rooms in universities by considering some constraints. Inconvenient and ineffective timetables often waste time and money. Therefore, it is important to investigate the requirements and potential needs of users. Thus, eliciting user requirements of University Timetable Management System (TMS) and their implication becomes an import...
متن کاملA Generic Framework for Modeling Decentralized Reputation-based Trust Models
Decentralized applications do not have a single centralized authority that can safeguard peers in the system from malicious attacks. Each peer is autonomous and must adopt measures to protect itself. Reputation-based trust management systems enable peers to develop trust relationships with each other based on their reputations. These trust relationships help a peer determine the trustworthiness...
متن کاملIdentity-based Trusted Authentication in Wireless Sensor Network
Secure communication mechanisms in Wireless Sensor Networks (WSNs) have been widely deployed to ensure confidentiality, authenticity and integrity of the nodes and data. Recently many WSNs applications rely on trusted communication to ensure large user acceptance. Indeed, the trusted relationship thus far can only be achieved through Trust Management System (TMS) or by adding external security ...
