Countering Threats in Decentralized Systems using Reputation-Based Trust Models: A Software Architecture Approach

Advisor: Richard N. Taylor, UC Irvine/ISR

Abstract: Open decentralized applications, such as P2P file-sharing applications, can contain malicious entities that execute attacks on other entities in the system. In the absence of a centralized authority that can help regulate the entry of these malicious entities and help protect against their attacks, each entity must itself adopt protective measures. Trust management has been found to serve as a potential countermeasure and has, therefore, received increasing attention from researchers.
